Saw it on Sunday, finally here to review!
WARNING: SPOILERY BITS BUT NOTHING VITAL REVEALED ABOUT PLOT.
And....I thought it was pretty lovely, actually. The opening scene was a little unneccessary (except for bringing about an Itchy and Scratchy cartoon that was better than the last few that've aired) because I've always felt that the audience-bashing the show's indulged in was a major jumping point.
But the movie itself? Just wonderful. It had a plot that actually hung together well (the pig was properly amusing and wasn't overused), Homer was only jerkassy only a few times, a plot that interwove the family together nicely (except for the Lisa subplot, which was lovely, adorable - total fic fodder *cough - but seemed to exist outside of the movie), and a serious, thoughtful meditation on these times we live in. Why can't the show be more like this?
What surprised me about the movie was that it was dark, even dramatic in tone, for a great portion - and I found that wholly welcoming. The sight of the Simpsons' house being completely destroyed and sucked into the center of the Earth, for all the times we've seen it burn and collapse due to sinkholes (nice callback!), is genuinely moving. More importantly, when Marge leaves Homer - as many times as they've sepparated on-show - this one feels real, possibly permanent, all due to its tone and J.K.'s boffo voice acting (the subtle, broken way she lowers her tone when she says that she's run out of excuses for Homer is heartbreaking). I'll woman up and admit that that scene made me cry. I'm even willing to accept that there may be a perfectly in-canon reason for that footage to exist, that's how in-love I am with the scene.
Then seeing all of Springfield in the state it ends up in. The penultimate scene is a nailbiter because we're emotionally invested in these people, and seeing the citizens team up to make a break for it is enlivening. Many scenes and moments were quite eerie and spooky! What the series has missed is its gravitas, and this movie has it in spades.
The audience I saw it only experienced one big LOL moment; the Wiggums/gun scene.
My hilights:
* Ned: *has revelation*
Homer: *fingers crossed and hoping* "GAYGAYGAYGAY"
* Wiggum: "They're China's problem now!"
...totally cheap laughs, I know....
* Anything with Moe, who was stellar throughout this.
* The woodland critter scene in which Marge and Homer horrify a bunch of big-eyed birds by snuggling.
* The entirety of the Colin/Lisa subplot. Can we hope he'll be a regular in the series? The hilight of their little romance:
* "I don't approve of suicide, but if you'd like to make a go of it - that would really cheer me up..."
* Skinner and Krabapple being together during the disaster, despite the fact that her teeshirt says he's not her boyfriend...
* NED WAS NED AGAIN! A geniunely nice guy who cares about his neighbors and in times of crises steps up and does the honerable thing. And when the Really Bad Stuff is about to take place...
* "Best kiss of my life." "Best kiss of your life so far..." *MELTS INTO PILE OF MUSH*
NEGATIVES:
* Why didn't they just have Rainer as the president? I could see why they made the twists-and-turns of Arnie being the chief executive, but Rainer being president would have added a whole extra layer of canonical pathos. We haven't seen him since the Greta episode, so it's possible he could have been elected.
* I didn't quite understand
*
OFF CHARACTER PROGRESSION THOUGHTS:

was an absolute rock star, and if her future!job doesn't have her ending up in the CIA or somewhere equally dynamic I'll be very, very sad.

was eight again! And adorable when she's got a crush. I love how the movie balanced her activism with her musicality and her innate girlishness, but was sort of dissapointed that she and Homer didn't come into bigger conflict. Then again, Homer had enough conflict in this movie to last for years.

was actually a balanced figure again - caught between his juvenile delinquency and his genuine desire to have attention and be accepted. He became the voice of reason at some point (which was really scary), but remained the bratty big brother/miscreant son throughout.

was herself!! I completely buy her reactions here...
J.K's voicework is heartbreaking. If she doesn't at LEAST get an Annie out of this I will be sad.
*

was a strange combination of his Pre-Season 10 and Post-Season 10 selves; for the first half of the movie he's in Captain Wacky territory, uncaring of the enviroment, victim to goofy physical humor, falling for his pet pig. But the big transformation that takes place in his character mid-movie ties back into the Homer I loved as a child - clumsy, aggressive, a little dumb, but a family man who loves his wife more than he loves himself.
QUESTION: is this the first time we've ever actually bluntly seen:
Did anyone spot their favorite supporting players in silent roles? I spotted Laura Powers toward the end in a crowd scene.
FANFIC PREDICTION: Lots of darkfic with a spattering of Colin/Lisa.
FINAL RECOMENDATION: It's honestly worth the money to see it first-run, especially if you've missed the "Lisa's Substitute" days; if you like an all-laughing, all-wacky! Simpsons, then wait for the DVD or the dollar theatres. If you're a Marge/Homer 'shipper, bring tissue. I, the person who perhaps overrates everything, give the entire production a hearty reccomendation and encourages you to come see it often.
FINAL GRADE: A.
