I don't want to give away any specifics, so as to not spoil the fun for anyone who has to wait until Friday to watch the new season. But I am sold! They brought it back great. Plenty of fresh and new while still retaining what's always worked and is familiar for lifelong fans.
My biggest concern before seeing it was that the riffs were going to be a little too topical to today's popular culture and would make references mostly for the younger generation - but that was not the case at all. The riffing was definitely at times making modern references, but nothing that felt alienating to me for not watching TMZ or MTV or whatever the kids today tweet about. It was sharp and funny and I can't wait for more!
