I sure hope you've got the budget, and cast/crew talent to pull this off.

A lot of the dialogue needs to be changed. Seriously. You're going to annoy a lot of fans with a bunch of those lines.

Batman cussin' has GOT to go. He doesn't in the comics, or the films, and it's not necessary here. It's fine for Wolverine cos, well.. he cusses. But not The Bat, man!

The killing of Gordon, and Bullock, and Joker, and Scarecrow, and Mr. Freeze, and other main characters has GOT to go. Are you trying to END the whole Batman continuity here? When The Batman KILLS The Joker (hypnotised, or not), it ends EVERYTHING. You should know better.

There's not that much of an ending either. Kinda' like this review!

Good luck, fellas!
