Yeah, I still enjoy them. They were a silly, fun take on sci-fi that I think sadly ended up today with a poorly deserved rap as being lowest-denominator repetitive humour. However, I think a lot of the early series probably wouldn't land for people who were born after ~2000, while the later series have intermittently weaker writing and rely a lot more on references to the early series.
I still rewatch it all the time, as do my family, it's a fantastic funny show that comments on the human condition, and the first episode still gives me fuckin' chills. But - its reliance on contemporary culture probably makes it a show that is "of its time".
EDIT - Plus quotes coming back to my head now:
"No silicon heaven? But where do all the calculators go?"
"No, human eyes don't have a zoom function." "But how do you bring a small object into focus?" "Just.. move your head closer."
"Relax the tax people aren't gonna catch you now." "What do you mean? Just because we're three million years into deep space and the human species is extinct?! That means nothing to these people!"
And every other line of Quarantine, obviously. What I wouldn't give to experience that episode anew again.
