I was a child of the 80's and loved anything with Muppets (Sesame Street, The Muppet Show, Muppet Movie, Muppet Caper, Muppets Take Manhattan, Muppet Babies cartoon, etc.).
Went to see the new movie last week. Fantastic! Not going to lie, I got a little choked up when Kermit walked into the rundown Muppet Theater for the first time in years, and looked around at the various pictures on the wall from the original series (had a picture of Steve Martin's appearance, and others). And then sounds from the original series echoed throughout (Pigs in Space intro, etc.). Took me back to when I was a kid. Also got a little choked up when they performed Rainbow Connection. Of course had to cough and act like I was choking down a piece of popcorn so the kids wouldn't suspect a thing!
Anyway, if you ever, at any time in your life enjoyed the Muppets, go see this one.
