I actually watched a couple of newer episodes last week, one was a kind of "Life Aquatic" spoof where Homer discovers an oceanographer/explorer may be his real dad (rather than Granpa Simpson), one where a lonely Marge makes some new friends who end up robbing Burns (?) and one where Bart spends too much time with Marge.
I have to say I did smile, even laughed a couple of times, but boy, it reminds me how good the show's golden age was
Recent episodes just arent as funny
Nearly half or more of the episode is taken up with something that has nothing to do with the story - see "Bart Has Two Mommies" or the episode where Marge gets lonely featuring a totally unrelated story about Lisa learning Italian from Milhouse (!)
