Shaky start, but picks up speed and is back in top form by 3x03. Given the S2 finale, it's sort of understandable, so I'm more forgiving of it than I am of 24. The 24 crew should have this down pat by now.

And no, don't skip S2. One because it's amazing and two because there are a lot of developments that you need to see in order to understand why the characters are acting the way they are.
