Worth seeing, if you like visually interesting films. Since Gondry does the writing as well as directing, the plot isn't as well-thought out and the story isn't as meaningful as you'd get from Kaufman. The animation was wonderful to watch, but not much happened beyond 'emotionally-troubled-young-man-meets-slightly-offbeat-girl-and-their-uniqueness-becomes-an-obstacle-to-forming-a-relationship.'
See almost every popular indie film in the last five years for other examples of this.
I don't mean to diss the film- I really did like watching some of those visual sequences. But overall it was just ok for me.
