It's really hard to understand a lot of the reviews that have categorically trashed the film here. I can appreciate that an older, or more sheltered, audience would maybe find the film a tad too raw and brutal to enjoy; I'm pretty sure that someone like my grandmother would have a minor stroke at some of the language used. Then again, maybe not... she's a game old bird, come to think of it. But if you recognise the world this film depicts with ruthless honesty, I think you'll find it resonant, at least on some level, and ultimately very thought-provoking indeed.
Basically, I think the major problem with a lot of the most viciously negative reviewers here is that they seem to be lacking a sense of humour. I found Closer to be a very dark, very bitingly funny black comedy. It's not easy to get me laughing during a movie, but I really did howl in parts of this one. But then, an instant later, one of the leads would make an unutterably cruel remark, or a profound comment, or a tragic admission, and that would act like a sharp blow to the stomach, and the laughter would dissolve into something a lot more thoughtful and poignant.
I'm not saying this is a perfect film, though. There were quite a few lines in the script that I felt I'd heard before in some other hackneyed soap opera of angsty relationships, such as 'Please don't do this' etc. Maybe it's because a lot of these lines were delivered without any real emotional oomph or imagination by Julia Roberts, and sometimes by Jude Law. Both of their performances were generally solid, but there were two particular scenes focused on both their characters which did fall very flat. Thank God for Clive Owen's performance- he was riveting. Natalie Portman also gave a fiendishly difficult role her all, and she was equally mesmerising for the most part.
I didn't find the ending of the movie crushingly bleak at all. It was refreshingly real... and I don't mean that as a euphemism for downright depressing; it was actually pretty comforting to witness things conclude as you felt it was fitting that they should. Above all things, Closer is a ruthlessly modern picture. That doesn't make it sound too appetising, I know, maybe it'd be more accurate to call it genuinely, unabashedly contemporary and honest. If you've had any kind of a patchy history to your love life, if you've lived a little and have some experience of the dating/mating game during the last couple of years, I have no doubt that you'll find a lot in this film that is familiar and well-observed. You've got to know the environment depicted, on some level, to be able to appreciate the satire, I suppose.
So if you haven't seen the film and are in two minds whether or not to buy a copy, I'd say go for it. It's a hauntingly memorable fable with an exceptional performance from Clive Owen, razor sharp satire throughout, and crikey- it'll make you think and laugh and wince and laugh and think some more.
