I'm blown away. Many reviews will say this is a time loop movie. (I would think something like should be spoiler tagged, but that's just me.)

It is not a time loop movie!

What I love about Triangle is that everything that explains what's going on is handed to us on a silver platter early on, yet the important bits to fill in the blanks are parceled out to the viewer at a near-perfect pace throughout the film.

The protagonist, Jess, goes for a first date on a boat with another couple, a single woman who the woman in the other couple invited along, and Victor, a young homeless man who the owner lets live on the boat. Aaaand now that I write that, I wonder if there is any deeper significance to those characters.

The film is beautifully shot. Some of the CGI is awful but that doesn't negatively impact the experience. The way it looked just made sense. I got the sense of a story being shown, and no feeling of an auteur showing off. I don't mind artsy films, but this film was well served by being shot straightforwardly...even if it may not seem straightforward at times. You may wonder why the POV of the camera suddenly goes from straight on the characters to looking down in the characters' backs from atop a staircase. Things like that.

The music and sound design were spot on as well. I just liked this movie a lot.
