For anyone interested in the original Battlestar Galactica, there's an fun blog (that covers a lot of sci-fi/fantasy tv) where the writer poses some interesting questions on points of similarity between Galactica and The Empire Strikes Back and return Of The Jedi.

There's also a section on the rarely seen Galactica telemovies that's a fun read if you aren't familiar with them

If you search around The 100th Planet, there's a lot of material for fans of 70's and 80's TV.
