This movie is the best of all the others from me and my brother's opinion. Though Idon't understand why they took out Mewtwo's origin. That would have better explained all of the questions of Mewtwo's behavior.
On top of which (drivng a little off subject), Anther movie about mew! has been announced and I'm soooo happy!! I just know it's going to have Mewtwo in it!! Come to think of it He really doesn't know much about the mew himself.
