Interesting analysis. I've never seen the show, though (no TV), so I don't have an opinion on the credit sequence.
PS to the reviewer: "Thusly" is not a word. Just say "thus".
Also, that's not a bowler hat. And one wears a carnation in one's buttonhole, not one's pocket.
Great Article by Selwyn Raab on the Boardwalk Empire:
Hat and carnation issues: corrected!
The show sucks. It has huge potential but its just a sad miss and incredibly hateful toward Christians and Christianity in general.
