Hashed.io
Recently imported all movie/tv/actor boards. The more I use it, the more I marvel and am stunned at how remarkable the UI is. I'll go so far to say that with some minor tweaking, it can easily trounce IMDB. It looks and feels completely modern, with lightning fast response times, streamlined interface (which is nevertheless extremely sophisticated), and with a wealth of features I never thought I'd see implemented.
I know many here were wary of a point system (a la Reddit) but I find it fascinating especially since you can apply points retroactively. You can even embed multimedia onto the posts, and yet the site still refreshes very fast. You can follow boards, although no individual threads yet, and the sidebar which contains recent and featured boards appear to be updating in real time. I'm so impressed, I can't stop gushing about it.
As a test, I was looking up some lesser known actors such as Nick Robinson, and they are there and all the posts are intact.
