The new opening credits kind of reminded me of the one shown after they released The Simpsons Movie. There were a lot more characters making cameos. And we got a chalkboard gag referring to HDTV.
I like how some things had remained the same, even if Homer did wind up Class President. Marge still went to Prom with the geeky guy. Homer would have had a job at the SNPP.
When Homer discovers that, when he ran for class president in high school and lost, the election was rigged, some "magic pasta sauce" gives him a glimpse of how his life would have turned out had he won.
