I liked this film for about the first 20 minutes,

Rating: 4/10 (19 March 2004)

then it became a jumbled, confused, and yes, tortured mess that did not know where to go or how to get there. The middle part, which was the memory erasure part, was over an hour long and was way too long and boring and convoluted, with terrible and choppy editing, as the story and the director seemed stuck, as in Groundhog Day, and didn't know what to do next to get out of it. Not well done at all, and it sure tortured me. Groundhog Day was a great film, by the by, and far superior to this flop.
More emphasis on the differences and similarities between the two separate relationships of the same two people would have been a great improvement and would have saved the film. Also, how others interacted with them in the two relationships, and how the two leads related to these people would have worked well too. The film became so unworldly and screwball that it lost its humanity and love until a conventional formula Hollywood ending "saved" it(for the box office).
Also, why did the filmmaker think that sloppy and careless Gen-Xer slackers with bad hair, hygiene, clothes, and personal behavior would be the best ones to do the critical memory erasing jobs??? Absolutely no credibilty there, and surely was done because the filmmaker is obviously "one of them"'. I say, Booshwah to that.
Spend your money somewhere else, you'll be glad you did. This film is going nowhere and will be another failure for Carrey.
