I'm afraid I'm not really up to date ... nor very involved in the fandom, but let's see.

Favourite character: Probably Nucky?
Least Favorite character: No one really, they're all at least interesting.
5 Favorite ships (canon or non-canon): Other than Nucky/Jimmy I don't really ship anything on that show.
Character I find most attractive: It's a show full of surprisingly unattractive men, despite the clothes they're wearing. ;)
Character I would marry: No thanks.
Character I would be best friends with: I think Nucky is a useful friend to have, no?
A random thought: I should probably watch the rest of season 2, but I don't really want to.
An unpopular opinion: I have no idea what the popular opinions are in this fandom.
Canon OTP: -
Non-canon OTP: -
Most badass character: ... I feel dumb for not coming up with answers.
Pairing I am not a fan of: Erm ... the whole story between the uptight cop and the annoying prostitute was just a pain.
Character I feel the writers screwed up (in one way or another): no opinion on this, really.
Favourite friendship: Is anyone actually friends on this show?
Character I want to adopt or be adopted by: -

My answers for stuff I have forgotten all about just suck. ;)
