I am a fan of the Agony Booth. The site has recaps of various movies and television shows that are entertaining and funny. The recaps are longer than traditional reviews, describing and commenting on the whole movie (or TV show). Although not strictly comics related, the site has recaps of various superhero TV shows (including Super Friends and The Incredible Hulk), as well as superhero movies (including Batman Forever, Batman & Robin, Superman III, and Superman IV: The Quest for Peace).
If you’ve never visited the site, I highly recommend it. It’s an excellent way to kill a few hours.
