I can't stand Crusher!
The only thing I don't like about this show is Crusher. He's not only selfish, but incredibly whiney, and constantly cheating. Sure, he never wins despite his cheating, but he often still gets what he wants, whether it's people sharing with him or his toy back after it gets stolen. If it were once in a while, fine, but every single episode has him like this. I hate it!
It's sad, because it's actually a great show in most other aspects, with lessons on things like magnetism, acceleration, and angles.
I also don't understand why Blaze has a driver. None of the other trucks have them. I actually don't remember ever seeing another human except him and a girl, but of course, she rides a purple 4 wheeler that can't talk; she doesn't get a monster machine!
