Overall very good, just not quite what I was expecting. It deals primarilly with '50s sci-fi. Nothing wrong with that but the TCM description (link above) which I had read before watching is a little misleading.
I wish they had covered more films. They spent a good bit of time on a handful of films and ignored others. What's there is good, I guess it would have been better at 2 hours. I remember when I watched it looking at the clock and thinking 'this isn't going to be long enough'.
Towards the end it does almost look like a WotW (2005) commercial. Which is fine with me.
