Situational Comedy
It's a "Situational Comedy", thus "sitcom" where they take their characters and in every episode they put them in some kind of a situation where comedy would then ensue. See "Friends"...
It's not funny if there is nothing to base the show around seperatly every week. Often they recycle old jokes and beat them like an orphan... Until finaly the joke gags on it's own vomit and dies horribly.
That being said, Red Dwarf was actually not a bad series, it had alot of the English dry humor. It was pretty funny at times, better imho then most Hollywood sitcoms.
I gave you a 10 for violence cause I've never seen anyone butcher a good idea like this before. I know you don't like sitcoms but jesus man, it's like you watched a half an episode. Then took a crap... Peering into your excrement you pull the best jokes you could from that. Then put those in... It's just a complete failure...
The short end of it is, it's crap.
