I finally found this on Youtube and decided to watch.
I really enjoyed this movie. Shaymin was just the cutest little thing, with all the Ash abuse, it makes the movie. I'm a bit dissapointed that the only attack Shaymin uses is Energy Ball. (Or was the big, green light Seed Flare?) Nonetheless Shaymin is my favorite legend now. ^^
Zero is a interesting character (though it takes him forever to really start doing anything), his endless army of Mangimite, Mangnaton, and Magnazone were the source of most of the action and very entertaining while attacking the train. But what exactly did Zero want with Giratina? Drain it's energy?
Regigigas did more than I though it would, but that isn't saying much.
The animation is nice and crisp, and I found the world breath-takingly beautiful. Dawn seemed... oddly drawn to me though. Sometimes her head looked misshapened.
Overall, this was a excellent Pokemon Movie, that meets most of my expections (which weren't very high after reading the summeries)
