I saw the movie last weekend and it is a lot of fun. I've been a fan of Malcolm Gets--his stage and TV work as well as his cabaret act for a long time and it's great to see him in a leading role.
I want to second what eslgr8 said about having out of the closet gay men in the leads. It's so nice to read interviews where they are not going to pains to say how straight the cast is, and the chemistry between Gets and Chester made it all the more enjoyable--they seemed to really have a good time. It's a really fun date movie.
