Is that Times New Roman? consider using another font (Arial/Verdana) for your side column. Generally it makes my eyes hurt reading all this but I like how the header looks!
I'd like it to be a bit more obvious what this site is, maybe try a tagline eg 'film appreciation from a genre fan' (sorry that's terrible but you get the idea!)
I'd also like to see more copy as generally I'm thinking "what is all this stuff?" about all your clips, how are you "adding value" rather than just lifting it off Youtube?
Remember to tell people what they'll get involved with in the forum, maybe 'hot topics'. Maybe look at how a thriving forum eg Mumsnet does this to encourage sign-up.
