Completely ruined by one scene

Rating: 3/10 (23 January 2012)

Bradley Cooper gets addicted to a drug that allows him to utilize 100% of his brain at the cost of some nasty withdrawal symptoms. During the apex of the movie, in a life or death situation in which he "needs" the drug to survive two men hunting him down, he literally starts drinking the blood of the other addict he just killed off the ground, and like Popeye eating his spinach, bounces up and handles the other two guys.
The ending was also horrid. They might as well filmed me at work staring at my computer for 5 minutes and showed that and they would've had the same affect. Can't recall a movie with a more anti-climactic ending...
Other than that, the first 75% of the film was interesting.
