Re: Did they make Mewtwo too powerful in the movie?
They made Mewtwo look too strong in the movie, because the movie, apparently, was pretty much focalizing Mewtwo. xD If any other Pokémon got Mewtwo's spot in the movie instead, I'm sure they would do the same. d:
Look at the Rise of Darkrai for example, Darkrai was considered the main Pokémon of that movie, and they've made Darkrai seem a little more powerful than Dialga and Palkia combined. d:
