Well, BSG has its moments of being pure kickass especially in the miniseries and first season. I think on a whole that it is well worth seeing, its just that the later seasons don't live up to the expectations of the first. But there are spaceships and gritty realism rolled into one, and that is always good.

As for fandoms I'll have to go with things I associate with you, so Tolkien - specifically the fëanorian aspect, Italian football and Greek myths (I blame the aegean punk for the last one) ;)

Speaking of the Greeks it should be mentioned that The Wire is in part inspired the old Greek plays and The Iliad. Seriously, you can have great fun identifying the Achilles character and so forth. Its about as happy as a Greek tragedy also...
