Is this the 4th movie? Cause if it is, the dub title of the movie was "Pokemon 4Ever".
Anyway, yeah, it's a really good movie. Then again, I've only seen the Japanese version of it (cause of Miramax's stupid limited release), so I don't know how the dub went.
Yet, I would rent it and see what I think of it, since the never before seen 4th movie short is on there.
