Im mostly finding that the formula and their absolutely refusal to abandon it is finally starting to be a deal breaker for me this year. It was fun in S1, I tolerated it in S2 because everything else was so good, but now, Im tired of it. Yes, there has undoubtably been some great development for Chuck's character this season, but its increasingly surrounded by elements of the show that feel stale and no longer work for me. Im not-so-secretly hoping this is the final season. The recent ratings would seem to support that wish, but the mess that is NBC means no show is truly dead.
