Ok, my add ons:
No muppet songs at all!
A LOT of potty humor
Too many muppets involved in the Convent scene (when they broke gonzo out)
They were not the muppets we know and love
So many old favetoite muppets are ignored and there's mabye 10 muppets that are focused on (what I mean is: it is all about gonzo, Kermit, piggy, etc. other muppets are just there)
And finally, my personal pet peeve: scooter had 1 line.. AND IT WAS NOT EVEN LIKE SCOOTER!
