This game is fairly dull and repetitive. I completed it in about 6 hours, though I had to force myself to, and that was mainly because I was looking after a couple of young kids that thought it was funny watching me laser everything. I would have switched it off after about an hour otherwise.
The levels themselves are tediously repetitive and the puzzles the same. Sure, the doors or locks are in a different place, but they're almost allways "send mooch to unlock a door or two so you can get in"... and other than using lasers to shoot bad guys, that's all this game has to offer.
The one redeeming feature of this game is that the electrical appliances are pretty amusing and varied.
THe film was fantastic, I loved it, and I will buy it as soon as it's released. The game is a poor accompanyment, and I'd avoid it. Don't even bother trying the 3D mode either - it makes the game look even worse, and you can't aim... assuming you can put up with the red/blue glasses long enough.
