15 Kochanski Mark II
Red Dwarf
Role: Reincarnation of Lister girlfriend as somebody completely different.
The painful truth: Mainly irritating because she wasn’t Clare Grogan, who was just ace. Quite why you’d replace a cute, fizzing Scottish ball of fun like the Grogan-Kochanski with a matronly English cold fish like the Chloe Annett version is a mystery not worth fathoming.
