A few things about the Betty White episode:
(1) It showed how weak the current cast is, especially when it comes to women. Kristin Wiig alone is not enough to carry the entire show, and both of the repertory women they have now are just not of the same caliber as the women who came back.
(2) It also showed how weak the writing staff is today. You could tell which of the sketches were written by Tina, Amy, and Molly, and they were the ones that stood out the most.
(3) One of Saturday Night Live's greatest weaknesses in recent years has been that they don't write to the guest host's strengths. Again, some of this can be attributed to having Tina, Amy, and Molly in the mix this week, but they knew how to use Betty White. They wrote sketches that were perfect for her delivery and her personality. It also probably helped that Betty's such an open book with everyone and has never been afraid of mocking herself. If only they could use every guest host that way.
(4) If you haven't seen "Life With Elizabeth" (which did NOT go out live, by the way, but was one of the first completely recorded sitcoms - shortly after "Lucy" pioneered the format, and one of the first that was syndicated instead of on a network) go to the Internet Archive and download a few episodes. I was so glad that they worked in a reference to that show in the monologue because it really is underappreciated today and shows that Betty White has always been as funny as she is today.
(5) MacGruber needs to die permanently. Even Betty couldn't save that tired schtick.
(6) Least funny sketch? "Scared straight." Also (apart from "MacGruber," I believe) the only one that didn't include one of the returning women. Shows the weakness of the current crop of men.
(7) Most cringeworthy joke of the night for me? Lawrence Welk bit about isn't it funny that he can say the 'th' in 'mother' but not in 'think?' Anyone who knows anything about language and phonetics, or can do a Brooklyn accent as a bunch of New York based comedians should do as second nature, knows that there are two distinct sounds for the 'th' combination. It's not funny, it's a clueless comedian grasping at straws. And the deformed sister isn't really needed, anyhow, since the Welk show was so high camp that it became self mocking. For evidence, go to YouTube and look for the clip of Lawrence Welk backselling "that great modern spiritual..." "One Toke Over The Line."
This was "Saturday Night Live's" best outing in years. Very little padding, very little cringeworthy crap. Looking at this show should give Lorne pause, because it shows how much potential is still there in the format, and that maybe he ought to do what the network has done so many times in the past: blow it all up and start fresh. The reason the show has lasted as long as it has is because when things get bad it can become an entirely new show. They did it in 1981, 1986, and 1995. They're long overdue for another overhaul.
