I get to be less and less of a fan, if I ever was one, of George Clooney. Outspoken "anti" making his money in movies that predominately feature?...guns.
As the last poster noted, they need to hire a consultant who actually knows what a gun is. And how to handle one and how to do some serious work on one. Not magically make a modern can out of some washers and a pipe. And, fill it with machined aluminum parts. When no machines ever get shown.
The thing I didn't get was the opening scene was a "job". I thought it was where he went to hide and got caught up with. Popping lasts nights girl in the back of the head would have meant something if we got a clue what that 'something' was. Throughout the movie, we see the Swedes send their 'killer' teams after him. I have to laugh about that. Not that Swedes aren't capable of handing out violence, I just don't think of their worldwide spy network as one to fear. At least in comparison to other countries. The bungling that they operate with is almost reason to turn the movie off (no I didn't waste good theatre money on this movie).
All in all, the movie is lucky to have only gotten as low as a 66% from Rotten Tomatoes. Lack of direction in where the movie was going and why is the big reason. Cudos to the director of Photography for making the girls and the landscape worth sticking around for. How Clooney got an oscar for this one I don't know. Same reason Tomei got hers for "My Cousin Vinnie". The Academy must've had a bad hangover and they voted for the first thing that came to them.
