Rachel McAdams is intriguing. I wasn't entirely convinced she's strong enough to carry a role in a show like this, but I thought she came out of the first episode quite well. Colin Farrell is obviously made for this (even if some of his lines were, well...), and I have no doubts about Vince Vaughn. The rest of the cast I'm not too familiar with, but I think this has potential.
Have no hopes of it holding a candle to the first season, which felt like one of those rare, cosmic occurrences where good things just come together (in particular Woody Harrelson and Matthew McConaughey) to form something unexpectedly awesome. Even if the plot infuriated me at the end, it was still a piece of television history.
