Live action? Not for pokémon.
When did a game or animation based live action go well. I guess the first Mortal Kombat movie wasn't that bad, and neither was the Super Mario Bros, cause it was just fun cheese, but just take a look at Dragon Ball, Garfield, Resident Evil and Twilight movies, I want to puke.
Oh wait, Twilight wasn't any good in the first place, imagine that.
