Seasons 1-3 are brilliant. Great writing, great cast, one of the best comedies from the early 2000s.
Probably could have left it there and the show would have been recognised for its quality.
Not sure why tv studios ever think it's worthwhile revisiting shows after long layoffs. Seasons 4-5 weren't necessary and were embarrassing additions to the original 3.
5 stars for 1-3. Only 2 stars 4-5.
