Hi, SKA! I went to see it on Friday and it was okay. It's worth seeing just for a perv, really and a bit of a giggle in places. :o)
The two friends I went to see it with were blubbing quite a bit, but it didn't really touch me. It wasn't enough like the book for me. Personally, I don't think Hilary Swank was right for the role as Holly as she wasn't convincing enough as the "greiving widow".
I would say go and see it, though, just don't expect too much if you're a fan of the book. :o)
