The bluescreen effects still hold up pretty well for 1992
Especially the long shot where Kermit and Tiny Tim are walking along on Christmas eve to go home, and there's even snow on his feet as he goes. Other shots are good but easier to spot as chroma-key, like when Rizzo falls onto the roast goose and the ice-skating penguins, but keep in mind that this was before widespread computer compositing--and from the same year when Alien 3 tried to show the Xenomorphs running with bluescreen rod puppets and ended up with a blurry mess. I've also always loved the lavish look of the sets and miniatures in this film.
High fives and corporate anthems, nothing comes to mind.
