So... yeah, after doing two episodes about "The Simpsons" still being funny, I realized I hadn't actually watched this year's Xmas episode, so I did. Fox made it available HERE on their website, though I watched it On Demand.
It's another "possible future" episode, this one set in a timeline where Bart and Lisa both grow up to be parents themselves. To my mind, it's easily one of the best episodes I've seen in awhile - good enough to have been a Season 5 or 6 episode (or at least a current installment of Futurama.) Seriously, give it a watch. (SPOILERS after the jump.)
This is the first "future" episode where Homer and Marge actually seem to have personality changes beyond "older" - Marge has a shorter temper and seems a touch jaded, while Homer is sober(!!!) and seemingly more intelligent and good-natured as result. I like that.
Running joke about Dearborn, Michigan is edgy as hell by Simpsons standards, to the point where it verged on being out of place. But yeah, I laughed.
So, at least according to this timeline, Lisa Simpson is bisexual as a grownup. I like that the "reveal" passes without comment, but it runs one extra beat so you can tell they wanted you to catch it. I know a few BIG fans of Lisa who I can picture turning cartwheels at this... and also a few desperate continuity-obsessives who'll be furious that this contradicts the character in the "President Lisa" timeline's claim to being "the first straight female president.
This is the first "Simpsons Future" I can say I'd be legitimately interested in seeing them revisit. In particular, I'd LOVE to know the story behind the blink-and-you'll-miss-it detail as to the fate of a certain ex-Krusty Sidekick - I feel like it must have been either Bart or Homer who finally did the deed, but I can't decide which would be more awesome (leaning toward Homer.)
