I just saw Batman Ninja... seems like a great concept for a Batman animated movie so... what went wrong??
Well... this is maybe the worst plot ever for a DC animated movie... starts whit Grood and a strange evil machine that sends every one (and I mean every one... heroes, villains and alfred!!) To ancient japan whit evil science!!
If you want to see Batman doing cool ninja stuff please stay away from this one...
Cheap dialogues... poor story and ridiculous stuff like a mecha castle fighting a giant monkey made of monkeys thats turn into a giant Batman when bats come to help in the fight....
If you love Batman, the ninjas and mechas do yourself a favor and ignore this piece of crap...
The animation is very good... that's the only good thing about it.
