Query: Painful to watch

Without repeating everything said before, this was one of the biggest disappointments I've seen in a few years. First I expected a lot more from Greg Kinnear and Matt Damon which are both very talented actors. Second this movie was about an hour longer than it should have been. Maybe they could have padded the material out to 90 minutes but to punish the viewer with TWO full hours of lame dialogue and lifeless acting is just criminal.Why on earth did they use Cher, who looked like she was wearing some kind of plastic mask the whole time and acted even worse.I just hope I can forget this film so I can stop kicking myself for buying it.
