they have said conclusivly that there ain't going to be one, sorry don't shoot the messenger. I think i would have loved a 4th but it may have killed it a little.They left it whilst it was still strong, and that what keeps it classic, just like spaced, only 2 serise, and still brilliant. I think the thing that kills good prgrams is when they have to make the funny strech over too many episodes, and that in my humble opinion is what was wrong with American comedy. What is it 24 episodes a serise? far too many to get them all stunning. Look at it this was you can remember every single episode of Black Books and what happens in it, can you say the same for friends?
