LD,
design wise, your boards are fine. personally, i think they're really nice looking! others might disagree, and think they're ugly, but... its all personal opinion, and everyone has their own.
as far as community goes, tho...
'entertainment' isnt, exactly, a unique idea. its difficult to put a new spin on it. thats why you're losing business -- users might go to your forum and think its just like every other 'entertainment' forum.
so, your quest is to make your forums better -- or at least different.
what have you done so far, to entice people to 'buy' your 'product'?
thats a great starting question for anyone with any of their sites.
look at all the different beers out there -- thousands just in america! and yet its budweiser that outsells all of them.
why? it doesnt taste really any different. its packaged nearly the same.
the difference is in its commercials! yeah, other major beers have just as many on the air -- bud budweisers' are always the best, the funniest, the most UNIQUE. thats their edge.
in the same line of thinking, your boards need something that sets them apart from other boards. perhaps you could create an ongoing posting game for your users! or maybe a new feature, where users earn avatars. start up a daily (weekly?) review sheet, where you discuss and rate the latest movies (but schedule the post, so that users know when to expect each new one).
it doesnt have to be anything overly complex or ellaborate or even time consuming. as long as your boards have some sort of feature that can not be found on (many) other boards, YOUR forums will be the ones that are visited.
and there y'go.
