Now, finally, after a few years and a DVD player later, I bought the movie, and I gotta tell ya, I regret it that I didn't see it in the cinemas... actually, I don't, because, well, I was "too old" for pokemon. That's the biggest bullpoo I ever heard. Well, sure, pokemon is mainly for young people, but I did enjoy the movie, for an 18 year old guy.
Well, back to the movie. The movie is great. I've seen the movie in Dutch first (because I'm used to the Dutch voices, and they sound better to me). The way Mewtwo's voice was used, it was as if Mewtwo was really in your head. But you'll need Dolby Surround for that experience. Also, the way the movie reffered back to the series, perfect. I mean, if you haven't seen the series, then that's okey, but don't look weird if you don't understand certain events and jokes and such.
The most unique thing is that this Pokemon movie really shows how much the Pokemon can care for their trainer. ** ENDING HINT ** You can mostly see it near the end of the movie.
Pokemon: The First Movie is probably the first movie that succeeded on following up their series successfull. It may not be a great movie, but it sure was fun to look at.
