I enjoyed this show a great deal. I didn't get to see the whole thing back when it was on tv, so I'm glad it's been released on dvd. The final episode cliff hanger, is very aggravating! Yet another example of great sci fi that was canceled by main stream television. I agree that perhaps it was better off canceled rather than ruined by money rakers with no love for story. I wish they'd had a bit more patience especially since it won some significant awards in the US and Germany. I enjoyed the casting, the creature effects, and the New Mexico wilderness setting. Too bad it didn't have someone like Joss Whedon to get it turned into a movie like with his canceled series Firefly.
Still, there is some great fan fiction out there that continues where the show left off. Check it out at: http://www.fanfiction.net/tv/Earth_2/
I recommend Arcole's continuation starting from: http://www.fanfiction.net/s/4110810/1/Blast_from_the_Past
Don't miss this great series!
