Kari, I wasn't able to see The Libertine because of a limited release, it wasn't shown at a cinema that I could get too. It had a limited release in the US too I believe.
I have finally got to see it though, on DVD. The US DVD release is July 4th.

It is not to everyone's taste that's for sure, given the darkness of the subject and being period costume and all, but I think it is an excellent film with superb acting from all concerned.
Sorry I can't give you a proper review, I am really bad at that sort of thing.
