The IMDb message boards are being shut down this month, and personally, I am glad.
I unregistered from the board years ago because I was tired of reading conspiracy theories, racism and sexism, hatred of EVERY movie and TV show, and other juvenile and unrelated content. The nonsense far overshadowed the legitimate commentary and questions. I was fine with someone stating that he didn't like a show, and telling legitimate reasons why, but that has seldom happened in the past decade.
The immature posters were also a reason why I started writing my own movie commentaries here.
