So I just watched Chuck, and it is also cool. So all in all, a good season for TV! It has a really good cast, and seems to have the right balance of humour and coolness. It has a similar vibe to the short-lived Jake 2.0, so if you liked that, you'll probably like Chuck too.
Also, turns out I was wrong about Eureka, only one new episode last night, so the finale isn't until next week.
