Yeah, I've seen everything except for series ten. Even read the books.
Once they got Kryten as a main character in series 3 I felt it started to take off, but once the Red Dwarf crew was resurrected in series 7 I felt things took a down turn. Though I still did enjoy series 7 and 8, and for many years found the, what I thought would be forever unresolved, cliffhanger ending to series 8 somewhat agonizing.
