I really enjoyed them, and I like that it's delving into the differences between the klingon houses. I also like the casting, everyone seemed to fit their rolls really well, particularly the Vulcan guy, can't remember his name, James Frain really suits being a Vulcan.
Not sure what's going to happen with the future episodes though, I've a feeling it will go back to the seven years since Michael joined the ship, because the Captain is in 15 episodes according to IMDB.
