Just had to bump this up as we recently discovered Castle too! I was a great fan of Firefly so this is just perfect. I love Nathan's character. I do have a little quibble though. Does anyone else think that his on-screen daughter Alexis is a little "too good to be true"?
I love the chemistry between Nathan and Stana. I'm also so proud that they're both Cdn, or at least have Cdn ties.
