Wow, you nailed most of those!
Anyway... as someone who has barely seen any 2016 film, let alone any big nominee, here's my pointless take on the whole Oscars, for anyone who cares...
First, I loved the Justin Timberlake opening. Very enjoyable and fun, I was shimming in my seat all the time.
Jimmy Kimmel's opening monologue, ehhh... it was, okay I guess. Overall, Kimmel played it safe most of the night. He rarely pushed the envelope, if at all, but he wasn't cringe-worthy either. He's a likable dude and he was pleasant most of the evening. I chuckled several times, but I don't think I LOL'ed at all.
The "candies from the sky" bit was cute at first, but he overdid it the 2nd and 3rd time. The tourist thing was awkward as hell, and probably even staged. He was best when he was in his zone, playing of his regular material, like the "Mean Tweets", which were mostly good, or his "feud" with Matt Damon. But he lacked anything truly memorable like Crystal's dance routines, or Ellen's "selfie", or anything that would make him stick in the collective memories.
I don't think there was a single memorable speech. Maybe Viola Davis, or Casey Affleck? Don't know.
Most of the winners went as expected, everything like clockwork. Few surprises.
The final gaffe pissed me off. I have to admit that, at first, I felt it was staged. Beatty's hesitation to read, looking around, then the mistake, it felt weird; as if the Academy had planned to do something to create publicity and stir things up. But anyway, after reading about the incident this morning and watching the video again, it seems obvious that Beatty and Dunaway were just victims (at least Beatty stayed there and acknowledged "his" mistake. Dunaway was probably already on her limo). But anyway, I feel sorry for everyone involved, although I really wouldn't put it past the Academy to stage something like this for the reasons stated above.
Overall, it was a flat show. Not one of those that have me going "OMG, that was awfullll!!!!" but hardly a memorable one. Meh...
