I'll put my opinions in, as a huge fan of both the Muppets and WWE. I've loved both of them ever since I was young boy, so imagine my anticipation.
I thought every section was pretty good, and the interaction between them was ok. It's not a secret that WWE have always respected the Muppets, they were not about to make them look stupid here. The moment I knew it would be alright was when they had a graphic annoncing they were on, and you could hear the gruff, 'smart', longtime wrestling fans cheer.
I did read that Statler and Waldorf were due to actually commentate on a match, but that match was bumped due to time constraints, so that didn't happen.
Another good sign was both Beaker and Animal were at the ringside area at various points... so the live crowd would have seen the performer in plain sight. In a different time, this might have been booed in the extreme era of 10-15 years ago, but with more families in the house, it was merely accepted for what it was.
We shouldn't forget this was a wrestling show with Muppet guest stars...in that sense, i reckon we (muppet fans) did quite well out of it.
