If you are into science fiction, old time radio, cult TV and fantasy I can suggest a visit to The Blog of the Cosmic Griffin.
I'm into cult TV and radio and this blog looks like being a good one. It's new, begun this month, but looks good and has great content. The current post is a review of the 1997 sci-fi film Gattaca. In fact I'm off to buy the film, the review has tempted me!
