Your website looks neat and tidy. I mean the contents have been arranged well.Try to put some color for the background page.You have used white color and it looks blank.
Green color in header .... Not bad but it would look more nice if you do something with blues. The ad on top is disturbing the whole page. Overall site is nice, neat. 6/10
The header could use some improvements, looks too plain. Other than that, it's fine, I'm not sure if that voting system is a good idea though, especially for the films that are split into different parts, as part 3 could end up in like the 3rd page, and it would make it hard for someone to view the whole thing.
I prefer the header to be centered, but I know some people like to align to the left. It looks a little odd with the ad above it being centered. Everything else is very basic, but that's not necessarily a bad thing. I agree that the voting system could mess up navigation on this site, unless you've already found a way to address this. I'd probably do away with the voting and just make the tag cloud more prominent.
