A severe disappointment. I enjoy the Game Boy, Pokemon, and even the TV show, and I expected the movie to be similar to the TV show, filled mostly with humor and cuteness and a few pokemon battles. However, the movie is not very much like the TV show. There's about 8 jokes in the movie, and the rest is an attempt at a dull plot with a predictable moral.
The initial 20-minute short was embarrassing to watch, particularly because of the 30-second pokemon interludes which can only be described as a sort of pokemon-fantasia.
Overall, I can understand why a pokemon fan would want to perhaps rent this movie, but I would highly recommend against it. I recommend instead renting one of the episodes, which are much more entertaining.
