I thought it was a good start. I chuckled a lot, but didn't laugh out loud hysterically yet. I don't want to sit here and compare it to the original Muppet Show, because it's not, and it's unfair to the hard work everyone put in for this and the past two films to keep the franchise alive. I think it shows definite promise. I enjoyed seeing the rats back, Rizzo included, a lot of the side characters like Uncle Deadly, and the various monsters. I thought the writing and jokes were pretty good, I thought the scenes with Fozzie and his girlfriend's family were the strongest of the whole episode.
I thought actually the weakest part was the guest stars. I still honestly am not familiar with Elizabeth Banks nor consider her a "big star" and Tom Bergeron to me is the guy who took over for Bob Saget on "America's Funniest Home Videos". I know he's an ABC guy now for Dancing with the Stars so it made sense to include him. I am looking forward to seeing the direction the show goes. I thought the film The Muppets was promising and Muppets Most Wanted was hilarious so I'm hoping the same thing happens to me watching this show and each week just improves.
