Take a look at our best and worst moments below.
BEST & WORST: The instantly historic best picture mix-up
After Warren Beatty announced La La Land as the best picture winner at the end of the night, the elated producers realized something seriously mind-blowing: the Oscars favorite actually didn't win. This has never happened before in the 89-year history of the Oscars, but here we are in 2017, and the wrong movie was announced as the winner (and yes, of course there was a Steve Harvey reference from Kimmel). Although it made for quite the awkward "WTF" moment -- and likely thousands of viewers are still wondering "how could this have happened?" -- it is arguable that Moonlight was in fact the right choice for the prestigious honor. Plus, poor 79-year-old Beatty explained that he had read the best actress envelope, which said Emma Stone, La La Land, so there was clearly more than one person to blame for such a Hollywood-shattering fail. At least there was no denying the show was live, eh?

BEST: Justin Timberlake bro-ing it up with Ryan Gosling
If there was anything '80s and '90s babies hoped would happen at this year's Oscars, it was that former Mickey Mouse Club buddies Timberlake and Gosling would reunite. Right out of the gates, Timberlake made that wish come true by hugging his childhood pal on his way up to performing "Can't Stop the Feeling!," but viewers even caught the two mingling once more throughout the show. If only there were a reenactment of "Cry For You" as well.
WORST: Nicole Kidman's ridiculous clapping
While cameramen were seemingly as excited about the Gosling/Timberlake reunions as we were, one thing they also couldn't keep their eyes off was the way that best supporting actress nominee Kidman was applauding her peers. The only explanation we could think of for the extremely awkward and bizarre clapping were the rings on her hands, but even so, you'd think there'd be a cooler way to avoid a painful clap.
BEST: Bringing the Hollywood tour into the show (including Gary from Chicago)
Kimmel decided to pull a little prank on a bus full of star-sighting tour attendees by making them think they were going to see an exhibit of Oscar dresses when, in fact, they were going to be brought into the real Oscars ceremony as it was happening. As one would expect, the tourists were awe-struck by the moment, which made for some hilarious expressions and soundbites -- especially from a man named Gary from Chicago (who even started trending on Twitter). The stars went right along with it, too, as Denzel Washington pretended to marry an engaged couple and Jennifer Aniston gave her sunglasses to one of the tour members as a souvenir. Needless to say, viewers at home were probably green with envy over those tourists.
?WORST: Kimmel poking fun at non-American names
Kimmel's dry, sometimes dark humor was definitely apparent during his hosting duties, but some of his jokes may have gone a little too far. Perhaps the most distasteful occurred when he mocked best supporting actor winner Mahershala Ali's name, as well as dissing one of the tourist's monikers (saying, "well that's a name" after she told him what it was) and suggesting that her husband, who was named Patrick, had a real name.
BEST: The Hidden Figures stars bring out one of the real-life stars
As one of three films based on a true story of the 2017 nominees, Hidden Figures paid tribute to the people who inspired the film by bringing out former NASA aerospace technologist Katherine Johnson. Although she didn't say anything other than "Thank you, very much," the twinkle in her eyes and smile on her face were enough to prove that it was a special moment for all.

WORST: The show length
Yes, by now it is practically a requirement for award shows to exceed the time its allotted. And yes, we love seeing as many filmmakers honored as possible during one of the biggest nights in Hollywood. But beginning at 5:30 p.m. PT and ending at about 9:15 p.m. PT, that is a nearly four-hour broadcast. Considering Kimmel had snacks drop from the Dolby Theatre ceiling three times (and every time the stars looked thrilled about getting fed), clearly even those in attendance probably wished it wasn't quite? so long -- even with the shocking finish.
BEST: The Rock's Moana introduction/Lin Manuel rapping
Whenever The Rock makes an appearance at an award show, it's almost inevitable that it's going to make for a standout moment. Not only was he looking spiffy in a blue velvet suit coat, but The Rock even paid homage to his singing role in Disney's animated Moana -- as a way of leading into yet another epic Lin-Manuel Miranda rap. Honestly, can you ask for anything better?
HONORABLE MENTION: The breathtaking staging
The Oscars may not have ended the way producers would've imagined, but one thing for which they can pat themselves on the back was how beautiful the stage looked the entire night. From Great Gatsby-esque gold fixtures, to dream-like blue backgrounds, to massive crystal Oscar figurines, the setting of the show was awe-inspiring throughout the whole thing.
