Eternal Sunshine of the Spotless Mind

Trailer for this movie is available in Quicktime now. The premise, as you'd expect from a Charlie Kauffman script, is intriguing: what if you could erase unpleasant memories? Jim Carrey has his unpleasant memories of his relationship with Kate Winslet slowly erased. But, as he does, he finds he's falling back in love with her.
I would like to have some unpleasant memories wiped. I want to erase all memories of having seen The Matrix Reloaded and The Matrix Revolutions, to go back to that time when, after having seen The Matrix for the twelfth time, I learned that two more entries would be forthcoming, filling me with a sense of giddy anticipation.
