I could see a MLP movie being the opposite, having a little girl (or girls) getting transported to a fantasy world, and just being an excessive number of humans in it. Like a cheaply done Narnia type deal with a couple name ponies in it. Still would suck, though.
While I did enjoy the Smurf movies, mainly due to the hammy Hank Azaria's Gargamel, I always thought that bringing them into a modern world was a huge mistake that was brought on by trying to make the whole franchise their Chipmunks. Though, as we all know, the Chipmunks always existed in the "real" world. I've always been horribly disappointed that they could have done a hybrid movie that took place in their world just as well. While I admit that the plot of the second movie was actually good, the only good thing to come out of those movies was the two animated side specials.
That said, the fact they didn't make a MLP movie like that (with TIm Hill as a director, perish the thought), and pandered to the existent Brony base by making a straight up MLP:FIM movie is pretty amazing. I just hope that with the TF cinematic universe and Bay finally out of the picture, the TF movie franchise goes through a seriously needed overhaul. There were sparks of hope in AOE, and the potential for a TF in space movie with the Quintessons as the villains actually had me excited. And maybe...just maybe... at some point, someone may just make a fully CGI animated Beast Wars movie. Yesssss.
