i’ve watched them all - and i definitely agree with what seems to be the overall feeling: season 10 starts the decline.
that being said, there are plenty of good and fine ones in the middle 20 (lol) to make the watch decent. i also think the newer seasons (maybe the past 3,4?) have more winners than the shows had for a while.
i think the only episodes that i find truly objectionable are the ones built entirely around either a real-life ‘celebrity’ or have a real life ‘celebrity’ play a character that is pivotal…those episodes i just don’t really watch (few exceptions, of course - i like the 24 spoof with kiefer sutherland and a few more)
