"I apologize. I know I left some of your favorite shows off this list. How do I know that? Because I left some of my favorite shows off this list. The happy and unfortunate fact is that there are far more than 100 great shows, and more created every year. Lists are incredibly important: they are how we define what matters to us, what we want entertainment and art to do, what we expect of our culture." —TIME TV critic James Poniewozik
It’s the concept that launched a million lousy pitches. (“He’s an uptight accountant in jail for securities fraud! His cellmate’s a fast-talking pimp! They’re the original odd couple!”) But this classic sitcom made lightning strike twice by casting Tony Randall and Jack Klugman as finicky Felix and slovenly Oscar, fitting the roles as perfectly as Jack Lemmon and Walter Matthau did in the film (based on the Neil Simon play). The pair were lonely ex-husbands—at a time when it had just become acceptable to talk about D-I-V-O-R-C-E on TV—slowly, reluctantly realizing their faults and culpability for their problems. Urban, urbane and stagey in the best sense of the word, this sitcom affirmed that opposites could attract an audience. I still don’t forgive it for the Lethal Weapon movies, though.
This remake ditched the melancholy of the BBC original (q.v.) in favor of a cheekier rebelliousness: a little less Man in the Gray Flannel Suit, a little more Office Space. It also has a deeper, diverse bench of characters, including schoolmarmish Angela, chatty Kelly, cold-hearted Ryan, creepy Creed, angry Andy and screw-you-guys clock-puncher Stanley. The carryover stories have been complicated as well, especially the Pam and Jim romance, which has allowed Pam more of an inner life and self-discovery. Still, I’d pay to see an alternate-universe scenario where Dwight Schrute meets Gareth. (And just so you don’t think I wimped out by including both on the list: I like it better than the BBC version. Let the fighting begin!)
