I loved Equestria Girls... I don't like the dolls, but the movie they had to make to sell those dolls turned out great. Good messages, solid characterization. I liked how they used the parallel universe trope to explain it (tickles my sci-fi loving brain).
The horse-to-human gags were great (Twilight's hand freakout, terrible handwriting, apple chomping and computer confusion...etc.)
Also, I adore the cafeteria song. Ahh! It has to be one of my favorite songs now.
Of course, I still love ponypony over humanpony.
