ok...in "Out Of Time" which is the last episode in series 6. The crew travels back in time. But even though they have travelled back in time, Kryten explains that they are 3 million years back in the past, Only still in deep space. Yet in the 1st episode in series 7, they return to the shipwreck where they got the time drive and travel back in time to earth to pick up curry for lister. How did they manage to get to earth. Why weren't they in deep space still?

Whilst i am here, i though i would bring up a few other mistakes i havnt heard mentioned before.

In marooned, lister askes rimmer what his 1st time was like, and rimmer explains it was in the back of his brothers car with a girl he met at cadet school called Sandra. Yet in Thanks For The Memory he explains to lister he had only done it once! yet he clearly explains he has done it twice! why cant he remember his only 2 times?

In Queeg rimmer becomes damaged due to the ship being hit by an asteroid. During the time before he is fixed, He takes on different personalities of the crew. Including holly, a doctor and oddly the cat. But why would the ship have any hollgramaic data on the cat. As he was not an original member of the crew and no one would of programmed it in!

The last main one i wish to point out is this. In Quarantine kryten gives lister what he calls a reduced amount of luck virus. you can see the quantity on screen. This luck lasts less than one minute. Yet in Back In The Red - Part 2 (viii) lister only rubs his fingers over the top of the test tube and receives lot of luck for quite some time. This is clearly wrong.

But, even after all these mistakes let alone all the other listed. This program is possibly the best ever, and still makes me cry with laughter 2day. so what there are a few mistakes, enjoy it for what it is.
