I liked this movie and didn't really like Eternal Sunshine enough to remember it.
I can't speak for anyone else, but I really related to the Stephan character. I mean, if he was a real person of course he would be an unlikeable sociopath, but as a movie character I thought it was funny and entertaining and truthful at the same time. I also really loved the parts where the Charlotte Gainsbourg in his mind would just tell him what he wanted to hear, and the him of his mind would get all excited, even though it was obviously not what the real girl would want him to do.
It's kind of cutesy and overly precious, but not nearly as bad as stuff like Amelie =X
