I hate practically everything with Ash in it... but yet I have a favorite movie. That would be Pokemon Ranger and the Temple of Sea. I mean, it focuses on May, not Ash, and Manaphy is just so cute!
The by far worst, though, is the Sinnoh trilogy. Specifically, Arceus and the Jewel of Life. I couldn't understand a THING of what on earth was going on! (I liked Shaymin in Giratina and the Sky Warrior, I must admit.)
What do you think are the best and worst movies?
