Topless Robot has posted a list of the top 10 sci-fi television shows that were canceled too soon.

I've never seen most of the other shows (and if a lot of America followed my example, that could somewhat explain their early cancellation), but I have watched numbers 1,2 and 7. Star Trek is an obvious choice for number 1 given that it is still the icon of science-fiction television.

I've heard good things about Max Headroom (number 3) and would probably at least watch it on DVD should it ever be released in the format. I disagree about the 1981 Hitchhiker's Guide to the Galaxy series (number 2) and think it works best at its current length. I find it interesting how the only reason the author wanted to extend Buck Rogers In the 25th Century was to see more of Erin Gray ("Off think. Off think. Off think").
