I don't get why people like it so much. It did start out well, but then it turned out bad at the end.
Let's look at the episodes:
312 New York City Serenade:
The episode was good. I liked seeing what has been going on with everyone, I liked the mystery revolving a new villain, alas it was kind of ruined by the promo. In addition, Emma totally did it with a flying monkey. which is hilarious.
Unanswered Question: Why did Zelena need Regina's blood? Fan's speculations or writers answering on twiiter is not good enough, Those kind of question should be adressed on the show.
313 Witch Hunt:
I liked this episode, It was the best episode of the season, I liked everyone's reaction to the new curse, Emma meeting everyone, Henry doesn't know what's going on, which brings a new dynamic to the characters and I especially liked Regina and Emma's scenes.
314 The Tower:
A filler episode and not that interesting. I didn't like the blatant metaphore of male being neutered. I hated their spin on Rapunzel, which is a fairytale about the overprotectiveness of parents and how they need to let their children choose their own paths, but instead they made it about conquering your fear, which was dumb, because Repunzel feared more about going home than being locked in a tower forever.
Unanswered Question: Why did Repunzel cry for help only to tell the man who came to help her to leave?
315 Quiet Minds:
Neal's death didn't make any sense and it was done poorly. You don't fake kill a guy and then bring him back only to kill him for good. It was obvious that it was done so Emma could be free to be with Hook cause the way Emma and Neal's relationship was written compared to Emma and Hook's made it impossible for her to choose Hook over Neal. It makes me angry because they took Emma's agency and that is not a good way to solve a love triangle. In addition, Neal was acting way out of character. He always ran away from Magic, He always knew that it is not the solution to his problems and still he insisted on find some for reasons. This was way out of character. Neal had so much potential as a character and had a potential to develop other characters - Rumple, Henry, Emma. He was connected to everyone.
316 It's Not Easy Being Green:
I hate puns - "It's the wicked west" even though Storybrooke is located at east! It's episodes like this that sometimes made me wonder if the show is really aimed for adults and not just children. As for Zelena's backstory - been there, done that. How many times do we have to see the villains who were unloved by their parents and abandoned? I also thought her motivation was weak - "You were born" woof.
Unanswered Questions: Why didn't Zelena use the shoes to go to Wonderland and confront the woman who actually abandoned her instead of attacking someone who had nothing to do with it? Why didn't she try to talk with Regina, who might have accepted her and let her live in the palace with her?
317 The Jolly Roger:
Another filler episode and the worst kind - a Hook filler episode! besides the boring scenes of Hook and his man pain, we got Snow and David acting stupidly and let a 13 year old to drive. The only thing I liked was Regina and Emma's scene and Emma's magic development.
Unanswered Question: Why would Zelena think that Emma would kiss Hook after her true love died five minutes ago? suddenly everyone forgot Neal ever existed? that lips curse was ridiculous
318 Bleeding Through:
RETCON! RETCON! this episode just retconed Cora's backstory and created massive plot holes! it ruined two great episodes - The Stable Boy and The Miller's Daughter and for what? plot convenience? this was actually the first sign that the writers just didn't care anymore.
Unanswered Questions: Why didn't Leopold recognize Cora in The Stable Boy? I don't care that says he did and they planned it all along - which is obviously false. Leopold was reasonable. and no reasonable person would mary the daughter of the fruitcake who tried to deceive him in the past. Why didn't Eva told Henry and his father about what Cora did? Why did they portray Eva as being mean when she actually did the right thing by telling Leopold about Cora and her schemes against the throne's succession, which is supposed to be considered treason and punishable by death.
319 A Curious Thing:
The episode that contradicts the "Dead is Dead" rule. The heroes kill innocent people and there are no consequences. Snow casts the Dark Curse and there are no Consequences. I admit that the scene when Snow crushes Charming's heart was touching and sad, but it was riuned by that ridiculous sharing a heart deus ex machina crap.
Unanswered Questions: Who were the people our heroes killed? why was it never mentioned afterwards? why didn't they feel bad after realizing they killed innocent people? am I the only one that is bothered about that? Sharing a heart - why was it possible? what are the consequences?
320 Kansas:
The Worst episode of the season where everything and everyone were just stupid. I guess they realized they had one more episode in the season and everything has to end (cause god forbids they won't do a filler in the finale). Se Emma goes to defeat Zelena even though it was established that Zelena's main goal was to take Snow's baby, so she really should have stayed with her mother and protect her, but of course David comes up with the ingeniuos plan that she should take the one person that can neutralize her powers to "protect" her. why? because the script says so, we have only one episode! so they go there to face Zelena and she decides to drown Hook and throw him in the pool that suddenly and conveniently was just there. Emma, instead of moving Hook or the water, decides to do CPR, FYI CPR != Kiss, so apparently inhaling and exhaling oxygen is like kissing and here I thought that kissing someone has to have romantic intentions. BTW, Emma and Hook's true love CPR does not break Zelena's curse, I wonder what it says about them as a couple (maybe they are not true loves after all). Zelena goes to the hospital ans since there is only one episode left, everyone is considerate and let her walk trhough and take the baby. Emma returns and explain to everyone that she doesn't have magic anymore (so much for going all that troubles and enact a second Dark Curse so they could find Emma so she could do... nothing - so much for being the savior). Henry tells Regina that she can do it if she believes in herself. of course she can do it, she saved the town millions of times because Emma is not capable of saving anyone, but don't you worry she'll get the credit for the defeating Zelena, otherwise this whole Savior thing deosn't really make sense. does it? Another thing that irritates me is how Emma is so inconsiderate towards Regina, Henry's real mother, about taking him back to New York and making it about Hook.
Honesly, I could have handled all the inconcistencies this season had if we got a better pay off, but this episode felt really ani-climactic and made the lead character a BIG MACGUFFIN! think about that - they did the curse so Emma could defeat Zelena, only she didn't! Regina could have done that the whole time! she just needed to believe that she can be a hero. That is ridiculous!
321/322 Snow Drifts\There's No Place Like Home:
There's nothing much to say about the episode other than it was a two hour filler that wasted our time because the only consequences were Regina's happy ending destroyed and Frozen cash grab.
