Pretty much Pokemon The First Movie
Is what it felt like but with CGI done pretty well (except for Gengar). If only Sonic learned from Pokémon. I sort of fell asleep for some reason halfway through the show but was there for the final battle with Mewtwo. Loved the cutesiness overall and interaction with Pikachu & Psyduck.
Think there was a problem with my theater because the sound felt standard and not the ultra surround one pays extra for (even though I didn't pay anything). Movie is somewhat to overly predictable depending on how you look at it. If you know nothing of Pokémon then this may not be for you as there are lots of references within the show itself including the slapstick comedy that Ryan does as Pikachu.
What Pokémon cards did you get? I got Pikachu and Psyduck before I realized there was Mewtwo and 2 other overly powerful cards even though I don't play the card game myself. :/
