I saw it at the cinemas when it first came out in April (and I wasn't even a dedicated FOTC fan at that point). I loved it - hilarious. I thought it was spectacular, and the soundtrack is amazing (I bought it like right after I saw the movie).
Intially, I read a super fantastic review of it which made me go 'Yep - definitely going to see this' (coz the reviewer is usually pretty harsh), but after I saw the film I saw that it got some pretty awful reviews too. Some journalists panned it.
I remember really enjoying it, even though it did run a bit long. I've been meaning to buy the DVD to see if I'll still like it as much at home. I find that nearly every movie is enjoyable at the cinemas (besides the massive flops). But I thought Rhys was amazingly funny.
