So true. A few years ago everyone was dogging on Landgridge's style, and I was one of the few going "wait a second, this is actually a pretty fresh and inventive take that works." NOW everyone loves it, but originally very few seemed to be ok with it.
Langridge has slowly become one of my favorite comic book artists... and not even for the Muppet Show either. I strongly recommend Snarked. It has a wonderful old school Thimble Theater (the Popeye comics when they were GOOD) quality to them, but somehow more modern. I also thumbed through "The Show Must Go On" at a bookstore yesterday. Now that's something I'm going to have to pick up when I get the money and find it again.
I've been reading licensed character comics for years, and the Muppet Show/Muppet Classics rank very high, if not the top of that heap. The only other ones I'd say are that great are the Archie Sonic line (as well as Mega Man), and maybe Boom's Darkwing Duck line. I don't count the old Carl Barks/Don Rosa Scrooge McDuck comics. But I've seen crap come out, even of my favorite characters. There were Ren and Stimpy comics where the artist literally pulled faces out of the style guide. Didn't even trace them... just copied them.
