The sudden realisation---
that Sir Aaron is voiced by Cilan in english and Cobalion in japanese.
Also, Clay, Hugh, and Colress voice Lucario in English while N voices (japanese) Lucario.
And the level of HoYay between Lucario and Sir Aaron....Like, wow. Not to mention the highly bishonen Sir Aaron.
I think this movie gets to be up in the ranks with M03.
I feel Kidd was highly unnecessary, though. She was practically a spotlight-stealer for May, Max, and Brock. Also, her hairstyle would freak even Iris out. And the part where Ash suddenly becomes athletic enough to jump on random friction-less platforms is quite, quite questionable. Finally, what mystery of mew, exactly?!
Nevertheless, still better than quite a number of pokemon movies.
