Very clean interface. Kudos to that. So far navigation feels great and is intuitive.
I like where you're going witht the medal system, though I would prefer if I could get a glimpse into what is required to earn medals. Some people, like me, will spend extra time with your site if we can see the goal we're trying to achieve.
Browse is pretty overwhelming with the amount of shows on one page. Maybe poll the user to figure out what they like and condense the list down. You may want to divide it into pages as well. Of course you can keep a 'show me everything' button, but I just wouldn't make that the first thing I see.
Briefly describe yourself is 100 characters. I'd like a counter or a visual cue for when I go over. (otherwise it just chops off my text).
It looks like when you 'heart' something, you can't take the heart back. For misclicks sake, I'd allow unhearting.
Like sajithw said, I'd like more information about the show. People in it, pictures, etc. Could scrub wikipedia or imdb for most of this info.
Good job! Keep it up!
