I'm am a bit of a weird age when it comes to my fandom of The Muppets. When I was born in 1982, The Muppet Show had already finished its run and two of the three original Muppet films were already released. However, the Muppets were still a big part of my childhood, with me watching everything from reruns of The Muppet Show to the Muppet Babies cartoon to Fraggle Rock.
That said, many of the Muppet movies I can remember the releases for came out after Jim Henson's death in 1990. Some of these, like 1992's Muppet Christmas Carol, are probably just as memorable as the original Muppet films, while others, like 1999's Muppets from Space are not so much.
