I think the worst thing changed was the ending at the beach... cutting off that loooooonnnnngggg walk while the end credits rolled? NOOOOOOO!!!!! That was one of the most memorable things in the film.

I'd say that losing the slow reveal of the Baseball Furies was a much bigger sin. The original version of the scene builds those guys up to be scary as hell and makes the Warriors look like they SHOULD run, while the DC version just uses the lame comic book transition to drop you in the action too fast, ruining the tension that was present before.
