hmm have you tried /r/movies/ ?
First, the user who used to make weekly box office analysis decided to stop doing it for free. Good for him/her, but that was a big blow for the subreddit.
Second, once you're long enough you realize how the hype machine is always there. From "leaked" picture to teaser to poster to trailer, all negative comments are met with "you can't judge until you've seen the movie" while positive ones are upvoted to the top. Not the only forum guilty of this, but it turns the subreddit into yet another arm of the movie PR industry.
I guess it's the inevitable end of all forums, so maybe this one will capture the magic that /r/movies lost.
What's the magic?
What does box office performance have to do with quality? Already looks like the subreddit has the wrong focus.
It also adds context to better understand what's at stake for movies based on distributor, producer and genres. When a horror movie costs 2M and a Marvel film 200M, "20M box office" by your favorite director can mean two very different things for their future.
But a Marvel film has nothing to do with quality.
It's fine if you're focusing on the movie business. Just don't confuse the two.
Like any social networks, the key to this website's success would be retention. I hope you find a way to make users come back often.
Still, a new community that isn't beholden to Reddit's quirks and whims is always welcome.
