Season 3 Wrap Up Cast
I didn't see a thread for this, so I thought I would start one. I happen to agree that Season 2 was better than S3, but I think it might come down to which characters you are interested in, and how well the show serviced that for you.
Minor errata on the cast: A-Ron said Peter Gould had relatives who consulted the show on legal issues. But it's really writer Gordon Smith, who's sister and mother acted as legal consultant to the show, going back to Skyler's IRS days. BCS 3x05 was dedicated to Gordon's mom, who passed this year.
