The Muppets Take Manhattan (1984)

This script is legitimately terrible, and The Muppets Take Manhattan isn't funny at all. Joan Rivers and Gregory Hines each have funny bits in it, but mostly this is just absurdly bad.

Just as an example of how terrible this thing is, at the end of the movie – which one might expect to be a moment when the muppets, in fact, take Manhattan – the muppets are performing their college show on a Broadway stage but then we move inside the show, in which a real minister is apparently marrying the pig and the frog. This is in the Broadway show they're doing, but also lots and lots of muppets are there, including the entire cast of Sesame Street. The pair are married and then... the movie's over. The plot of the movie is completely given over to the wedding ceremony, and whether or not the show the muppets were doing for their Broadway audience was a success or not, we shall never know. I am imagining, however, that their show was a success, because for some reason people in the muppet movies seem to enjoy the muppets' musical performances – except, that is, when the plot dictates otherwise...
