It's not just sf, there's crap characters in every genre. But often how many crap characters a show has depends on the show's overall attitude. Some shows have an outlook that leads to lots of crap characters and some shows have an outlook that leads to good characters. Also, who plays a part can have a big effect. A good actor can salvage a part and a bad one can ruin a part.

I find that a lot of characters I dislike a lot, I'm not keen on the actors either. And with characters I'm very fond of, I often like the actors too. An actor can't help but bring a lot of themselves into a part, their own deeper nature is all they REALLY have to work with.
