Nope, sorry I really didn't like it.
Flat, boring characters you don't care about, zero character developement and a very boring, cliched story that has been done a thousand times before. That basickly sums up Steamboy, oh I forgot: it really drags too.
But yes the music and animation were quite good...comparatively.
I can't believe the same guy did Akira too, have you seen that? A much better film imho.
