worst ending possible

Rating: 1/10 (9 January 2011)

had a lot betting on this film, researched about it, and had my hopes that would be one of the greatest... saw it on the premiere and then.. well i'm a dude that doesn't analyze the movie at the core, but this ending, man.. it ruined the rest of the experience. To ruin such a great idea. A technical genius who is somehow able to commit revenge murders from his jail cell. He doesn't hide the fact he's a killer; in fact he announces each murder just before it happens.
Technically everything was possible and the method very cleverly hidden so I was kept in suspense until the last 20 minutes when the cat was let out of the bag too early. The ending is the worst in a big production movie so far. Trowly technically improbable, illogical, and in my opinion it spoils all the character development made until that point and wastes the opportunity for a much darker ending with a more satisfying outcome.
my girlfriend like the ending, but i decided never again re-watch this one.
