Query: Brilliant! - An early peek at what Joss Whedon can do!

This is one of the best TV series, not just Sci-Fi series, I've ever seen. Its well written, entertaining and so full of wit that you've got to watch it at least twice to catch everything. Cancelling this series was a horrible decision that proves TV networks are not to be trusted with shows of this quality... If you're a fan of space, westerns, Joss Whedon, Nathan Fillion or just like good TV that is well written, buy this!
