So, just saw EQG copy.pasting my blog post about it.
Not perfect, but it was the best it could possibly be given the inherent limitations of the concept. Everything DHX could control was freaking amazing, the crap Hasbro forced them to do, not so much.
Hate the concept still, and still find it kind of insulting to regress the ADULT mane 6 into teenagers, not to mention demoting Celestia and Luna from physical goddesses that control the sun and moon and rule a kingdom... to high school principals... Yeah.
So yeah I still have issues with the whole concept, but everything about the execution was as great as you'd expect from DHX and I did enjoy it for the most part.
Nitpicks, the whole Flash Sentry character could have been chopped out without losing anything and he felt really forced and the crush/romance scenes were the dumbest one in the movie. Sunset had no real characterization beyond generic evil alpha bitch, and the sudden turn around at the end was BS. I'm saying she was just faking it to try and get out of trouble as much as possible. Luna just looked weird, the rest were okay, Luna, really really off. And Celestia sounded really off, really flat, dull and unemotional.
Like I said, horrid concept, but DHX did the best damn job they could with it and made a pretty decent and enjoyable movie.
