I thought BCS was a masterpiece. A 6 season masterpiece based on a comedic relief supporting character from BB, supported by other amazing characters some of whom were based on just one off, throw away lines in BB.
It started off as just a fairly light hearted prequel spin off, but ended up being both a prequel, and a sequel. To me, with the way it fully encapsulates BB (not to mention all the BB timeline flashbacks woven in, which add key little bits of context to BB events), it now seems like the parent series to BB, rather than the other way around, which is some achievement given the quality of BB itself.
