I just love bossy women. I could be around them all day. To me bossy is not a pejorative term at all. It means somebody's passionate and engaged and ambitious and doesn't mind leading.
I think it is very sad that 'sitcom' has become a pejorative term.
The term 'genre' eventually becomes pejorative because you're referring to something that's so codified and ritualised that it ceases to have the power and meaning it had when it first started.
