At the end of the movie when the big electric sign falls, first it's swinging side to side. But right before it hits Carter, it's swinging front to back, which is impossible to have happened.
I agree. Also when Clear yells for Alex to watch out for the bus, she intervenes, right? So why did the sign swing for Alex again. Wouldn't it have gone for Carter? As long as I'm going on I, might as well add that i don't think that the computer screen would have blown up like that it would have just short-circuted. There. I'm done.

The sign wasn't supposed to hit Alex, even though it almost did. Carter was FATED to come in right there. If Alex wouldn't have almost been hit by the sign, then Carter would have never "saved" Alex, and then Carter would have never died.
