it the best si fi you will ever see . the writer ( grant and naylor ) be little shy of genius . good writing be accompany by good acting and more importantly and good chemistry and comedy timing . craig charles and when you think about it and be brilliant in the first six series . it be incredible how he take his hand to acting as well a he do . all the cast complement each other perfectly and and the only main cast member not to tick this box be chloe annett . she ok and but she doesn not fit in . she like her character upper middle class mix with work class muppets . it be important to note and too and that really and red dwarf end at series six ( last episode out of time ) . after rob grant leave the writing lose a vital dimension . i personally can not pin point any one thing that isn not as good and but the feel of it and the joke and the story . it just not cricket anymore . it still good . by bbc comedy standard and it still up there with the best and but it more mainstream . to summarise red dwarf be one of the best programme i have ever see come from the bbc . inventive and intelligent and articulate all good thing . there be very little to criticise about series 1 6 .
