Thought the opening episode of season 6 was brilliant- all the way through you feel something's going to happen. But I didn't enjoy the Kevin Finnerty diversion, at alll. The final episodes though, particularly Kennedy and Heidi and The Blue Comet, were breathtaking.
Speaking of which, I watched the final episode of season 5 of the Shield last night. Oh. My. God. Unbelievable stuff. Can't wait to see how it shakes out into season six.
