A group of my friends and I maintain a (private) google doc of shows/games/books/movies/etc we have watched/read/etc with ratings and shorts reviews for the others.

Even without the review element its nice to keep track of what you have watched.

I spent a good while looking to see if there is/was any kind of open source self-hosted IMDB style thing I could throw on AWS we could use instead of a goole doc but doesn't seem like there is anything. Anyone come across anything similar? My next step is to roll my own and maybe hook into a few APIs so we can get thumbs etc.
