"Cheers represented writing, acting, and directing at the very highest levels, and Sam and Diane remain the gold standard for a complicated, fascinating relationship on TV. Many have tried to equal their chemistry. All have failed. Television may never see another Roseanne, but I find myself constantly yearning for another Cheers."
-Shawn Ryan, creator of The Shield, wrote a nice piece for Vulture's TV comedy tournament "Sitcom Showdown," comparing Cheers to Roseanne before rightfully concluding that, although both are great, Cheers is the best.
