Thing is, that it was good, but only good and somewhat misleading. First off, the number 23 is of less real importance then one might think given the build up and focus early on in the movie, not to mention that the DVD jacket has the number 23 inscribed all over Carrey’s face.
That number really doesn’t have a whole lot to do with paranoia associated with the 23 enigma, (as implied in the early parts of the movie, and as well even in the opening credits as dates in history flash across the screen suggesting an unsettling connection with the number 23).
(SPOILER ALERT) No, in this story, the number 23 is a mere trigger in facilitating uncovering psychological repression. In that sense, it’s more of a gift then a curse (given the clean conscience ending). That’s the part I feel misled about. If you want to see a movie or story where a number or figure has a profound and disturbing effect on the main character(s), watch pi (directed by: Darren Aronofsky) or Uzumaki (written by: Junji Ito).
(SPOILER ALERT OVER) If you see this movie, keep in mind that it is more of a mystery movie where the number 23 serves as a mechanism to connect elements of the story. Focus on the tag line, “The truth will find you”. Now about the performances, they were good except for when some of the character behavior was impossible (Virginia Madsen playing Robin Sparrow in particular, but bad writing is likely to blame).
Overall, the movie is good enough to maybe catch if it ever comes on T.V. I wouldn’t recommend to go out and buy it however (like I did). If you can get away with renting it, do that.
