The impression I got from Spaced is this; it was a decent show by people who could clearly do something really great. It's like Reservoir Dogs, yeah, Quentin made a really good movie, but it was more that he showed promise that he could do something really great, and then he went and made Pulp Fiction. So, yeah, I see no reason to remake Spaced. It's combining two ideas (The Office being a hit and Shaun/Fuzz being a hit) that have no real corelation.
