I felt that Sucker Punch fits this. They had some cool dreamy sequences, which looked good in the trailer, but then you watched the movie and those were kinda it. I think they tried to get a little bit of depth in there by making a sad story to tie the dreams together, but to me at least it felt shallowly deep 😛

Life of Pi

I call it Cinematography: The Movie

And yet I didn't remember the plot at all until reading that page. I just remembered the two main characters and the main setting.

Michael Bay. Although The Rock is hilarious.

Speed Racer. It was a blast. Sometimes Style is all you need.

Avatar, all of them.

The first one existed purely to show off 3d film technology and push the limits of CGI.

The sequels false started under the premise that the first one had anything past colourful lights and sounds.

Also, Tron: Legacy, which I am very fond of because it's essentially a Daft Punk music video.

Valerian and the City of a Thousand Planets

Absolutely stunning visually with writing that, even if it had been good would never have succeeded because its stars had exactly zero chemistry.

The Expendables franchise

One of the best "all style" movies has to be:

"The Good, The Bad and the Ugly."

Equilibrium.

More recently, Tron Ares.

Avatar, most marvel and dc films, most nolan films

The Fast and Furious movies literally started as an excuse for Paul Walker to drive his cool car collection, so I nominate those

The Tree of Life from 2011. I felt like half the movie was just shots of the universe with music. It was pretty nonsensical.

The Star Wars Sequel Trilogy (7-9). There's lots of cool-looking shit going on, but taken as a whole, it's completely incoherent.

Neon Demon but in a good way, the style becomes the substance. Love that movie

I’d argue visuals are a pretty major part of a what makes a movie a movie, so you could argue this is a case where style is substance. You’re not watching Tron for the story.

Enter The Void is pretty good.

Saltburn

Just about anything from directing team Hélène Cattet and Bruno Forzani (Let The Copses Tan and The Strange Color of Your Body’s Tears)

Drive. I LOVR the movie, and LOVE the soundtrack, but it's a run of the mill movie.

Speedracer

Angels egg. I get the idea but dam that was an empty movie. Whole thing could have been 12 frames.

Enter the Void is pretty bad

It's been a while since I've seen it, but Crank. All I can remember from the movie is just fast-paced action and stressful panic of doing everything to stay alive (Speed also comes to mind here), but not much in the way of drama or character development.
