Everybody has their own definition of funny, and, believe it or not, everyone sees their own muppets. ("One man's muppetology is another man's belly laugh." Some folks who love muppet movies dislike TMS, and vice versa.)
Myself, i sometimes think that Muppets strength lies in carefully chosen and chiseled archetypes (so
"you can say 'I know who that guy is!'" -- Dave Goelz) jazzing over contemporary tropes, which allows them to be both contemporary and timeless, and so on -- but i'd be first to admit that simply liking them works just as well.
However -- and i have a very expert confirmation to that -- there is some basic quality to the Muppets sense of humor that is largely missing from today's "edgy" entertainment, namely --
[33:01 - 33:47]
-- be that nostalgic and outdated or not, that's one thing I'd hate to see them lose.
Would it sell today? From what we saw in
another thread, Muppets theatrical release would hardly become a Marvel-sized box office hit -- dedicated cult following is more their thing. Full-size TV series were compromised by generally cold 2015 reception (even if fans liked it). So yeah, I think shorter and more flexible "Muppets Now" is the best thing they can do at this point to gain popularity. Time will tell.
