As a long time fan, the last series just didn’t do it for me.
I think the thing that made the older series so good was that behind the gags, each of the episodes usually actually had quite a decent sci-fi story driving it along.
The last series was just the same old gags with no real story. Look at Lister! He’s such a slob! And Rimmer, what an anal jerk! The cat’s really vain and stupid isn’t he! Oh, and what about Lister – look how much a slob he is! and so on.
Actually that’s one of the other things. Since about the time Kochanski came on the scene in an earlier series, they made the cat really stupid. He was never stupid before that. Vain yes, but not necessarily stupid.
