The website is basically a social media website for moviegoers. I found it about a few months ago and absolutely fell in love with it.
You can use the site to track which movies you've seen in a diary, rate them out of five stars, and also write reviews. You can also create lists (Top 10s, Genre Specific, etc.) and have a watch list. You can follow other users to see the movies they see and their ratings/reviews.
I have MoviePass and am a film major, so I got to the movies or see movies a lot. It's a nice way to keep track of the films I've seen and I actually write reviews for every movie that I've seen.
Here's my profile if you want to check it out. There's a pretty small user base but it would be a lot more fun if there were people I could follow!
