My name is John Loengard, I am writing this as I may not make it through the night.... On ITV4 tonight (in the UK) they are rerunning the excellent 'Dark Skies'. This is a scifi series set against the backdrop of real events.
The first series was set in the sixties, so we have JFK, civil rights, Gary Powers and LSD. The next episode was to be the 70s and so on.
The series is well put together, and later episodes show Jeri Ryan before she became familiar as Borg. Sometimes months elapse between episodes, which can be interesting. Also, I would advise you not to become too attached to certain characters, they won't always make it!
Well worth trying to catch. I have never seen this released on DVD, but would buy it instantly if I did!
