They probably will ruin it – reboots usually pale in comparison to the original series. I do like spin offs. I have been watching a new series called Shifting Gears – staring Tim Allen and Kat Dennings – seems pretty funny so far. Cheers!
99.9% of all reboots can't come close to the original. That's usually because most shows are tied to the time, circumstances, and audience of when they came out - and those elements are constantly changing. What was funny, challenging, or contemporary in one era isn't relevant in another.
That's funny; I only just started watching the first season and think it holds up perfectly well. I'll be interested in seeing what they do with this reboot—which doesn't mean I expect it to be nearly as good.
I think it might hold up because of the timer period in which it takes place. Comedies from a time prior to everyone getting offended by everything everyone says (think Blazing Saddles) wouldn't make it.
