Michel Gondry, who directed this, also directed "Endless Sunshine Of The Spotless Mind". That was a great film. I would say that "La Science Des RĂªves" is OK, but only that. Thematically it is similar to "Endless Sunshine Of The Spotless Mind" in that quite a bit of the plot takes place in the mind of one man, but whereas "Endless Sunshine Of The Spotless Mind" was a warm experience, this one is a cold one. Gael Garcia Bernal tries hard, and some of blatantly primitive special effects are quite wonderful, but I just didn't care one way or another. It's a kooky and strange film, and irritating, and is definitely not as good as "Endless Sunshine Of The Spotless Mind".
Maybe I just wasn't in the mood for it. Another day and I might have thought that it was wonderful.
