Premise: 10/10

Its the Batman. Batman is like combining Jet Lee and James Bond. You don't really need a better premise for a movie. This time its Batman fighting the Joker and Two Face, so its naturally epic.

The Joker: Infinity/10

The Joker has always looked fairly dumb until Dark Knight. Heath Ledger made the super-villain super awesome. The Joker doesn't look dumb for once and is a mega bad ass. Just look up the pencil trick. The costume was redone and manified to levels unknown.

Action: 10/10

Batman + Joker = fighting + explosions. There is a perfect balance of the standard Batman fighting, Batman v guns, and explosions. The Joker makes for some intense moments.

Plot: 10/10

The Joker's on the loose. There's a new DA. Batman impersonators are everywhere. Batman's gotta lay down the law, and he does. Its Batman gone bad and it is freaking awesome.  

Just watch the movie. You just need to watch it, not read an article about it.

Overall: 10/10
