Chuck was better when he used to constantly flash, we need to see more of his abilities but they seem to be stuck on having him surrounded by an insurmountable amount of force and him fighting his way out. When they aren't doing that they are constantly talking about his relationship with Sarah, which I have never really cared for, but it has become even less plausible now that he has started working out and come into his own whilst she seems to be fighting an uphill battle to look good. Strangely enough I find the story of a man with a super computer in his head trying to defeat a team of super evil spies more plausible than Morgan dating a hottie.
We need to get back to Chuck doing missions towards an overarching mission, but I guess the lack of continuity is more down to the fact they want to leave Chuck as a completed work and they never know if they are going to get cut or continue.
