Just saw it (Brentford's arthouse cinema first with the new releases!) and yes, it was touching but I thought it didn't really have an ending. The story is very mainstream Hollywood, it's told in an offbeat, quirky way but I had hoped there would be some kind of conclusion to it even if it didn't have a predictable happy ending.
I think Gondry over-reached himself with this film. The best bits were the little surreal touches like the flicker when magnetised Jerry walks into the store, or the magnetic urine attracting debris as it flowed away. Maybe the director wanted to say something about the power of cinema and the importance of telling a good story, but I thought the conventional plot got in the way. And as others have said, the music was intrusive - even if Michel Gondry played the drums!
