I, too, am late to the reviewing game (busy working weekend) but I figure I might as well offer my two cents on the whole Gagapalooza thing.
This was SO CLOSE to being a decent production. Just a little bit more effort would have taken a jumbled assortment of Gaga concert clips, somewhat-awkward celeb-Muppet mixes and decent Muppet-only material and made it a smoother, more enjoyable special. As it was, Mrs. Otter and I spent the bulk of the 90-minute running time shooting confused looks at each other. (She nearly bailed on it at the half-hour mark.)
Count me in on the camp that felt this was rushed together to promote Gaga's new album (and, to a lesser extent, to promote MMW). I'm also among those that felt Kristen Bell's segments served no real practical purpose (the first bit where she used Piggy as furniture while getting Gaga's autograph was kind of funny but every subsequent appearance got progressively odder).
Oddly, I thought a lot of it worked or was at least close to working. The dressing room scene and the audition reel felt like classic TMS fun, and it was great to see the Electric Mayhem in the "interview" bumpers, as well as the Gonzo-Rizzo pairing and the Chef-Beaker-Animal trio. And I like the over-the-top twist on Piggy's "Santa Baby," which took it a step beyond her previous renditions of the song.
I didn't always enjoy Gaga's concert footage but I actually found her charming in the scenes with Kermit. The "mutual admiration" clip had a classic-TMS feel to it (I'd love to know exactly what was inside Gaga's head when she stared off into space and murmured, "I need a swamp") and while the intro to "Gypsy" could have been a bit tighter and less ad-libby, as a musical number it actually seemed to work. (Steve Whitmire really nailed his duet vocals IMHO.)
Great blooper reel too. Statler and Waldorf looked and sounded like their classic '70s/'80s selves. And what can I tell you, there's just something fun about seeing our pals The Muppets singing and dancing to a pop number, even if it's something like "Venus" or "Applause."
No, it won't go down in history as a holiday classic but it did what it was supposed to - set things up for the new movie and prove that The Muppets belong in the modern media world.
Remember:
(1) Lady Gaga actually WANTED them involved (I was actually touched by her very sincere-sounding intro to the whole special) - and;
(2) We've been grousing a bit about the ratings for this special but it actually tied Glee (which, bizarrely, ALSO had a puppet theme) and that's no small potatoes, gang.
And, all things being equal, it's just nice to see Jim Lewis' name among the closing credits for a Muppet special after all the work he's done with them over the years. (If he did nothing else besides ghost-write Kermit's Before You Leap book I would still be grateful for his efforts.)
