I highly recommend Firefly, it's a great show, and very smartly written (the great thing about Joss Whedon shows is that the characters tend to act like they've watched a show or two from their genre, and thus don't act like complete doofs).
If you do end up enjoying the show, there are also some tie-in comics that expand a bit on the characters.
I haven't watched Firefly (but I'll get to it, eventually), but I have seen Serenity (which was amazing), and Nathan Fillion is amazing in Castle
And thanks a bunch Satin! Adorkableness is the best kind of dork
