The trailer for The Simpsons Movie is out, and guess what. It sucks. I think we can safely assume from this that the movie will target the show's current (17th season and counting) viewership, with the violent visual gags and dull pop culture references, and not the show's original fans, who used to enjoy quality, truth-biting satire and multi-layered wit and characterization.
Naturally, a show in its 17th contiguous season will have had many styles and many audiences, and a "movie" could only appeal to a few of them. I suppose it makes commercial sense for the movie to go for the show's current audience. But I think those of us who could re-watch anything in the first 8 seasons repeatedly and still have a good time but can't get through a recent episode once without retching are entitled to feel a little disappointed.
I lost interest several seasons ago, and at the time didn't pay much attention to why. Now I realize that it was/is the absence of subtle and not so subtle political skewering that I really miss.
