Ugh, as if shoehorning licensed IPs into the first movie wasn't bad enough already. Their version of Batman was basically every Batman parody that's been done on the Internet since Christopher Bale supplanted Adam West, and everyone else was a random cameo that had no effect on the story. And they were all poignant reminders that even Lego can't get people to buy their toys without making them all tie-ins with some movie or cartoon.
