I never made it past the first episode of Boardwalk. I watched the first one dazed with a fever and have them backlogged, but barely remember it now and I don't want to re-watch the 1st one yet am not ready for the following ones - I should get my ass in gear, or make sure to make that my TV fix until things pick up in January.
PD: Surprised you like Spartacus so soon, I watched it starting on Ep. 4 and it was a pretty laughable, but enjoyable guilty pleasure. I do admit that each episode seemed to build in quality but only ever rose to the level of surprisingly wonderful trash by the end. If you're already on board in the early episodes you got some good times ahead.
