A couple of things i don't get with the back to earth episodes.
Rimmer, what on earth is he doing as a hologram? he didn't die at the end of series 8. This clip found on youtube shows a finale for series 8 that wasn't shown at the time.

Also the idea that Kochanski would rather leave the ship to spend the rest of her life alone than with the crew after dumping Lister is a bit tenuous at best.
The show in the past has ignored a number of things from previous series though and i suppose it's sticking with that tradition.
Although i quite enjoyed the 3 episodes can't help feeling a little disapointed with it, sometimes it's best to leave it alone rather than try and return and create a finale that was too short and clutching at way too many straws.
