On the whole, it was a reasonable first episode but still not a slam dunk. There were more than a few amusing moments, but the plot itself had a very obvious conclusion that anyone with any brains would have seen coming a mile off.

But the producers have realised that ultimately the spy stuff isn't what they're great at and that it's the relationships between the characters that are going to be the draw if anything. Unfortunately, while just about every other character in the show is proving interesting - whether it's Morgan (Joshua Gomez) and the other IT guys now promoted to the opening credits, 'Captain Awesome' (Chuck's future brother-in-law), or the reliably right-wing Casey - Sarah and Chuck are still damp squibs.

Sarah's marginally more interesting, but still there essentially to look hot without exhibiting too much by way of personality, while Chuck is still more of a comedy set of geeky attributes without anything really to make him unique beyond his unfortunate situation. The attempts to make him more dynamic and 'spy-ier' mean he's going to be even less of an individual as the show goes on, if they're not careful. Here's hoping Bryce, Chuck's old roommate and Sarah's old boyfriend, will get to be a regular, because the show could do with some more tension.

If you've never watched it before, it won't be too hard to work out what's going on, thanks to the very newbie-friendly intro at the beginning; old hands should be prepared for more of the same, without too much format-tinkering at all.

Here's a great big six minute montage of season two clips shown at ComicCon. It's not the highest quality mind. I've also included one of the 20 odd random promos NBC's put together, because it includes Captain Awesome, who is, let's face, awesome.
