I just discovered Christopher Mills' Space: 1970 blog. In case you haven't heard of it, here's the blurb:
This blog is dedicated to the science fiction films and television series of the 1970s - give or take a few years (say, 1969-1983) - including such nostalgic favorites as Star Wars, Space: 1999, UFO, Space Academy, the original Battlestar Galactica, Jason of Star Command, Buck Rogers in the 25th Century, Logan's Run and many others.
But be warned: I still love these productions with all the enthusiasm I held for them as a kid, and they will be treated here with affection and respect. If you're looking for someone to snarkily denigrate "old" movies—or like to do that yourself—you've come to the wrong site.
So journey with us back to the days when special effects were created by skillful hands and spaceships were detailed models, when robots were obligatory comedy relief, when square-jawed heroes and cloaked villains battled among the stars -- and the future was fun!
The blog is very nicely done, including some great Star Wars content. Head over and have a look.
