Watch the alternate ending...

Rating: 6/10 (24 November 2011)

At first I thought it was a pretty good movie. The story went forward very well. There were subtle hints hidden here and there that pointed towards an interesting ending. Unfortunately the ending did not live up to my expectations (or that of all other people I asked about it). Also all the hints here and there didn't make any sense any more.
A few months later, I had the chance to see the original ending, which was replaced after a negative test screening. It was exactly the ending the movie needed. I don't know what kind of people the audience of the test screening was made of, but it seems they were somehow intellectually challenged.
Thus, if you happen to get your hands on a DVD or Blueray which contains the original ending, skip the 'fixed' one when the showdown in the lab begins and switch to the better one. It will return a meaning to the movie.
I'll give the cinema version 6/10 and the original cut 8/10.
