I personally thought he was absolutely adorable. :3
I really didn't like Shaymin much in it's fly form, but he was still cute. :3
His voice in fly-form did kinda remind me of Tails as well. D: Maybe that's why I didn't like it much ..but probably because it just looked and seemed much more cuter normal. 8D
I liked the movie. I thought that reverse world was intense. Like I wish I was there while watching it. It just looked and I could actually kinda feel how cool it looked and felt to the characters.
And I loved when Shaymin would turn Ash's head to the right side, then the left side, very quickly while trying to figure out which way to go. "THIS WAY...NO THIS WAY!" xD
(: Nice movie.
