The Oscars' Best, Worst & Weirdest Moments: Long-Awaited Wins, Surprising Upsets and Failed Jokes

This year's Academy Awards had some of the most memorable moments in Oscar history, but not all of them will be good memories...

This year's Academy Awards brought out the biggest names in Hollywood for a night of fun and mutual back-slapping. Even under the shadow of a highly publicized diversity controversy, the show was still an enjoyable journey through the past year in cinema, with enough real surprises and upsets to keep things interesting (and enrage those participating in Oscar pools).

From some long-awaited wins to a number of powerful musical performances, to some questionable jokes and disappointed losses, here's a look at the best, worst and weirdest moments from the 88th Academy Awards.

BEST

Chris Rock's Monologue Intelligently Tackling Diversity

Before the Oscars even began, Rock made it clear he was going to make the diversity controversy the centerpiece of his monologue, and the move paid off with a timely, intelligent roasting of Hollywood racism, overblown outrage and outdated stereotypes that made it one of the most memorable Oscar openings in recent memory.

Leonardo DiCaprio Finally Wins!

We had to wait all night to see Leo finally take home the gold, but it was great to see the hard-working star finally get recognized (and, of course, talk about climate change). Now it's time for him to relax a bit and maybe star in something a bit lighter -- a romantic comedy, perhaps?

Lady Gaga's Performance Brings the Audience to Tears

Lady Gaga delivered one of the best awards show performances ever with her Oscar-nominated song, "Til It Happens to You," which took the entire audience's collective breath away. There wasn't a dry eye in the house.

Jacob Tremblay Freaks Out Over the 'Star Wars' Droids

Could the 9-year-old Room star be any more adorable?

No. No, he could not.

Dave Grohl Leads Emotional 'In Memoriam'

The Foo Fighters frontman delivered a touching cover of The Beatles' "Blackbird" for this year's In Memoriam segment. It added a heartfelt, classy touch to the emotional segment. Although that wasn't enough to get Juliette Lewis to forgive the Academy for leaving her late dad, actor Geoffrey Lewis, out of it. (They also
failed to include Abe Vigoda, which is simply unacceptable.)

WORST

The Girl Scout Cookies Sale

Chris Rock helped his daughter sell Girl Scout cookies at the Oscars, and they actually made a ton of money. However, the segment just kept going and going, and eventually only served as a reminder that we still haven't gotten around to buying our own Girl Scout cookies yet.

The Revenant Bear

The bear that attacked Leonardo DiCaprio in The Revenant also got tickets to the Oscars, but the newly crowned Best Actor didn't find that joke to be funny at all.

Lady Gaga's Loss to Sam Smith

We're not here to slam Smith or his Oscar-winning James Bond song, "Writing's on the Wall," but come on! This was Lady Gaga's category and everyone in the world -- except for the Oscar voters, apparently -- knew it.

Chris Rock Makes Jokes About Asian Kids

The host tried to make a joke about race and politics when he brought out three Asian-American children on stage, dressed in suits and ties, and introduced them as the accountants for PricewaterhouseCoopers. Rock then went on to joke about child labor when he said, "If anybody's upset about that joke, just tweet about it on your phone, which was also made by these kids."

We get what he was going for, but the way the joke fell painfully flat speaks volumes.

WEIRDEST

Why Was Stacey Dash There?

Stacey Dash was brought out as part of a joke. Then she walked off stage almost as quickly, leaving most confused and some a little angry.

The Play-Off Music

When the speeches went a little too long, winners didn't get played off with the traditional, slow orchestral score like in the past. This year, rather, they got rushed off with some of the strangest musical choices of all time, including Wagner's "Ride of the Valkyries." It felt more than a little insistent.

The Oscars' Cinematography

ABC

Who thought the down-low-while-panning-around angle would be a good idea? Every time anyone was presenting the nominees in an acting categories, it was a confusing, nausea-inducing mess. It's the Oscars, not an experimental art project! Keep it classy and simple.

Sylvester Stallone's Surprising Loss

When Mark Rylance beat out odds-on favorite Sly Stallone, the world was shocked. We're not knocking Rylance's performance in Bridge of Spies (which was admittedly incredible), but this came hurtling out of left-field considering the score of high-profile wins Stallone has taken home this awards season. Also, it would have just been nice to see the man behind Cobra, Stop! Or My Mom Will Shoot and all three Expendables films take home the Best Supporting Actor Oscar.
