I think one of the worst part of the movie was the junkyard part. Him searching for the wooden horse, great, but they could have cut everything before that.
Cop flies over a junkyard, and random crazy people try to take him down like they can just shoot down a police car and get away with it. They get blasted to bits by Wallace Corp. Then he casually walks into building nearby and a bunch of kids are working there (what for, who are they, where from, who is cutting their hair and feeding them and buying all the toilet paper?). All so some guy can say I don't have the paper, someone took them.
I think it would have been much better just having him going to an abandoned factory in a dangerous part of the city or whatever, maybe fight some hoodlums if they really wanted some action, and then search for the furnace.
There's a lot of things that could have been shortened in this movie, this one definitely stuck out.
edit: Also is it me or there was almost no other cars flying around in LA?
