Basically, a place to talk about the times the show really missed a chance to do something great (I wasn't sure where to put this so if someone puts it in the Rant&Rave section that's cool).
Mine are:
Doing a female Hook (sorry Cols I love you) or even Milah as Hook (which would also open up another Snowing parallel because "Captain Hook's a girl?" "Woman.")
Paralleling Emma killing Cruella to save Henry with Liam killing the crew of the Tempest to save Killian.
Ending the show on Emma's birthday and having a parellel to one of the most iconic scenes from the pilot. Or ending it on Emma's wedding, that works too.
August as Baelfire.
Red Beauty.
Using the Dark Swan arc to resolve the Charming family issues and Emma's baggage where she can finally take it out on the people who caused it.
That's all I can think of for now anyway.
