Personally I’d go with Independence Day if I had to pick a movie that felt the most 90s.
The Sandlot
Yall probably forgot about Hackers because it’s a documentary but it’s pretty 90s
HACK THE PLANET!
the fashion, music and hyperbolic/complete misunderstood depiction of cyber security cements Hackers as the quintessential 90s movie
I know a few other people have already said it, but I’ll agree: Hackers, 100%. Late DOS/early-GUI computers + skate punk aesthetic? Can’t get more '90s than that!
I feel like Forrest Gump might deserve consideration, but I’m not sure it tops some of the other picks here.
Edit: Also Aladdin and The Lion King
Second post, but I realized the answer might actually be Teenage Mutant Ninja Turtles 2: The Secret of the Ooze.
Late to the party: Scary Movie
Interesting that Point Break (1991) and The Matrix (1999) book ended the decade. Point Break focuses on white 20 something kids that dropped out and started surfing, the The Matrix focuses on a 30ish white guy going through an existential crisis. At the beginning of the 90s there was still some hope, that a person could find a small counter-culture and create if not a wealthy life, of something satisfying. By 1999 all hope was gone.
Point Break would be my pick too despite the fact the early 90s had many sensibilities that look more like the 1980s to us now.
The Matrix
Wow, I forgot it came out in 1999, I guess, technically. It’s one of my favorite movies ever of all time, but it was too far ahead of its time for me to think of it as 90s movie.
Speed or mallrats depending on what kind of vibe you’re going for
edit: upon reflection I will change my Sandra bullock movie to “the net”. Terrible, but strong 90s vibes
Ninja turtles or surf ninjas
Man we had a whole ninja thing for a while there didn’t we
Can’t believe no one mentioned Men In Black and Mulan.
The Big Lebowski
Great movie, but what makes it about the 90ies.
Main characters are mid-life Vietnam veterans, the movie made White Russians cool (probably more from the cult following it got in the 00s), also bowling alleys( and LA ;) had their heyday in the 90s
The super Mario bros. Movie
Ace Ventura
I was going to say The Mask
I was thinking of that one too. Many of the movies where Cameron Diaz plays the protagonists love interest can be summed up as a quintessential 90’s movie.
I heard animals in there, Ventura. I heard them again in there this morning, scratching around.
I’m saying Fern Gully.
