Where are you from?

(MOD): Let's get back to the topic.

I think Jared Gilmore is a weak actor, and combined with some silly lines, 

"It's cheesy and it doesn't lie" (214 or 215)

makes Henry at times annoying. I also felt that from season four and onwards, Jared's acting ability becomes more noticeably weak. I guess he was fine in 310/311 and I don't remember him in Dark Waters other than him saying "Hey!" or something when Hook tosses his pop tarts.

His character also gets scattered, I guess, starting in 3B. Regina misses him for one year, and while it's tragic it can't hurt as much as being orphaned for 28 years, so when they reconcile it comes off as a little cute but mostly meh. The producers also suddenly depict their relationship as it was absolutely perfect prior to Snowing's curse in 3B, but it really wasn't since they barely interact in 3A as an actual son-mother relationship. 3A proves, "yes Regina loves him" but doesn't show if she can manage that (i didn't explain that very well). I also think that convincing your son is crazy and sending him to a psychiatrist to protect your curse (a whole other tangent) from whenever he realized that Storybrooke is weird (I imagine him noticing the lack of aging and time was the implication of Henry being sent to Archie's before even getting the book) is some sort of abuse. 

With that being said, I don't really think Henry as a character ignored Emma but it was just quite apparent the writers themselves ignored writing more for that relationship (which isn't very different but i think it's different enough to be worth adding).  

Jared is/was a child actor. I wouldn't expect much of them. People are too hard on child actors, especially for a fledgling pilot. The only thing A&E could do is replace him after achieving the first season, but Adam and Eddy appear to be the types that try to hold onto actors.

Henry (1 to 6) suffers a tad bit from the pillar-style of the show (which is fairly common but it gets more noticed based on strength of writing  and length of series).

Emma was the golden pillar with three silver pillars (Regina, Rumple, and Snow...who was replaced by Hook). 

If you see how early on (when I felt the writing/show was more "reali" and less campy) Belle was just an extension of Rumple's story, but you couldn't tell as much of that until Season 4/5/6. You probably questioned it in 3, but you knew in 4 and beyond that she could hardly exist outside of Rumple's sphere.

The same goes for Henry.

Emma shared Henry with Regina. Regina has the villains of the episode and dragged Rumple (a pillar) into the fold. Snow was her own pillar and hosted David and Ruby, etc. It was like a 4 star solar system.

But eventually Snow and David both entered Emma's sphere and Hook did so as well, but was strong enough to be a pillar unto himself to some degree. So, Emma's sphere got crowded and that ended with Henry being "pushed out". Regina didn't "take" Henry's character, but they simply absorbed so much into Emma that Henry got the backburner when it came to Emma-Henry time.

Other than that, it's just the writers not fully realizing their story. Lying to a child for years and manipulating him is abuse, but the writers like to use deep situations but tread in shallow waters.

Also, you can tell there was conflicting beliefs in the writers' room. Lana did push for more Regina-Henry, but regardless you can tell it was more of a positive than a negative as we can see how Rumple and Belle sort of turned out to be in the end. In layman's terms, they set up something good and then to shortcuts to fix it to get to a happy ending....which happens for neaelry every plot and character arc.

in some way i am agree with you but after season 4-5 Regina seems take the place of Emma how mother maybe i wrong because i read many people said about many Henry-Emma moments in season 4 and 5 but i don't remember if anyone could be more cleary what episodes it happened

In Season Four we have him going to Emma to deal with her powers going wonky, I can’t remember anything else but there are others. 5A has a lot of moments with Dark Swan and Henry, he tries to trust her, it doesn’t really work, finding Violet’s horse etc. The problem is, like Esk mentioned, she has so many people whose main relationships include her that she just can’t spend as much time as Regina who only had Robin and Zelena, Emma had Snowing and Hook who have more screen time so Henry has to float towards Regina.
