Few TV genres are as tricky to get right as the science-fiction series. However, this also allows for there to be an unlimited number of sci-fi shows with different tones, scopes, and stories depending on the platform they're coming from - be it a big-budget network smash hit, or a smaller and more intimate cable series. There are some excellent current sci-fi shows on television - but which do you think are the best?

It's time to pick the best sci-fi shows on television right now - those you think everyone should be watching. These are sci fi TV shows or sci fi series that voters have agreed are the best of the genre - at least for the current crop (we all know Battlestar Galactica would outrank them all!).
