re: Members....I implore you to help me decide on a show to watch.

If you want pure entertainment without too much intellectual challenge, watch 24 (5 seasons at least). It is brilliantly done and very addictive. I powered through all 8 seasons on netflix in like 6 months and thoroughly enjoyed myself.

The best of the shows you listed is Boardwalk Empire. It is really a masterpiece on par with the very best of serialized cable TV shows. It is as good as any theatrical release movie of recent years. Powerful and creative.

Dexter is novel and interesting for a while, but ultimately the writers get pretty lazy and fill the script up with too much bullshite. It's good, but third on your list.
