Not totally awful, Jumper is mildly entertaining, despite having Hayden Christensen in the starring role. Why does he keep turning up in movies that seem halfway decent? Just seeing his face, or his name, makes me want to avoid anything he is in...and this one was no different. Jumper, while mildly entertaining, is sure not spectacular, nor really worth watching, as it doesn't add anything really unique/new/special...whatever...to the world.
Maybe if they had spent more time developing the story, instead of having his character spend the first half of the movie jumping from place to place, and mostly into banks so he could steal the money he uses to live off of (for eight years!) without ever once trying to get an actual job and repay some of the stolen money as he had promised to do. He makes himself out to be a good guy, but he's not that good, if he continues to rob banks for a career.
Can't really say much else about this. If you happen to pick it up, it's not completely awful...but there are MUCH better titles out there, so why waste your time and money??
