Results are usually "pretty good", but that's nowhere satisfying for a connoisseur such as yourself.
We're working on that though, but we'd much rather have people talking about the movie than about the torrent. A movie is art, it's emotions, stories, parts of our childhood. Much more interesting than a bitrate, a codec, a PSNR level.
But in my opinion, even to a less powered user, it's still important to know if he is going to watch a DVD-rip or a russian-dubbed camrip.
We'll add a dropdown for alternative languages etc., and subtitles, but we got to breathe a little first. Lotsa things in the issue tracker.
As for discussions, unless you have some new way to find movies (which would be really cool), it's more important to see the quality of the files we're downloading. Even allowing user ratings of the specific torrents would help.
