Finally something different, if not new! (Possible Spoilers)

Rating: 8/10 (30 April 2003)

I highly recommend watching this movie.
This move is a dark, eerie and stimulating roller coaster ride from start to finish, which continues to surprise until the final scene, two seconds before the credits roll. What makes this movie different than any of the other movies of recent note, is that all the phenomenally acted characters in this movie only exist as the different personalities of a mass murderer - due to be executed in 24 hours.
The portrayals of the different personalities and their extremely complimentary contrasts reinforce the amazing depth of the mass murder's multiple personality disorder. The visualization of multiple personalities trying to co-exist within a single mind and body, indirectly, gives insight of how challenging it must be to treat such a disorder. Moreover how a doctor can encounter any level of success when the personalities themselves all have independent wills to live and survive.
At the same time this film, in a possibly unintended way, presents an interesting case for not executing a convicted criminal because he's mentally ill and makes an argument as to whether or not that is the right way to handle things in the very last scene of the movie. If a discussion about the treatment of mentally ill criminals takes place, after watching this film, you might have to consider that as one possible motive behind this eerie movie.
In a really long stretch, but a possible on, you can draw small similarities to Fight Club, but in this case there isn't just one alternate personality - there are several. In addition the alternate personalities are more tangible, in terms of how you could see each of the different personalities existing in the real world.
