Usually we're used to think of Jim Carrey as a comedy actor but in this film he shows that he's capable of dramatic roles, as he had done in "Truman Show". In this film, he tries to forget a failed romance with the irreverent Clementine (Kate Winslet) through a procedure that is, in practice, a brainwashing. But he regrets that with the process ongoing and tries to find a way to keep his memories. The film seems quite original and, in fact, the script has merit for trying to create a romantic comedy on a premise so different from the normal, but a large part of the plot is highly predictable. Another problem was the dialogues. In a film so light and so romance-oriented why insist on profanity or heavy slang? Some special effects look good, in particular the fading things and the passages from one memory to another at random, allowing us to have a wider knowledge of Joel's past. The soundtrack is quite kitsch and match the taste of both main characters but displeases the ears of the audience. Carrey was perfect in the main character, maintaining a good chemistry with Winslet, who also didn't disappoint. The rest of the cast (where we can see Elijah Wood, Kirsten Dunst or Tom Wilkinson) do their job satisfactorily, but leaving room for the main actors to shine.
