I once took my grandfather, a retired commander of the Land Army, to watch a leftist comedy. While I liked it, he was somewhat uncomfortable, but we watched it till the end.

A couple months later, he wanted to take me to watch a documentary on the life on a wooden ship over months, maintained for historical conservation. I'm not going to say it was the biggest turd I had ever seen in my entire life, but it was a serious contender, but nonetheless I had committed myself to watch it till the end because my grandpa did the same effort for me. In the end, it was him who asked me to leave early because he was bored.

Not a terrible movie by any means but Doctor Sleep. Poor elderly folks just weren't prepared for certain events

Freddy Got Fingered. One of the only movies I've ever walked out on

I can only think of one. The original movie of The Barnyard. It's a kids movie, of course, and it was never going to be great, but kids were asking to leave that movie. That's impressive.

Idk if this counts but me and a friend of mine went to go see the movie Skyline and no one walked out because no one else was there in the first place ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

Tree of Life (2011)

I was into weird movies at the time, and still am, so I went alone to some small theater that was showing it. A few people walked out in the middle of the movie because after a full hour, nothing noteworthy actually happened. At the end of the movie when the lights went on (and still nothing actually happened the whole movie) everyone who was still there looked around in confusion and just started leaving. I had no answers either.

The nutty professor 2

Hedwig. I thought it was such a beautiful movie and about half the people in the theater left.

I never saw people walk out of a terrible movie in the theater except myself, when my girlfriend, my roommates and I walked out of Johnny Mnemonic. After hearing about the dolphin, I think we made the right move.

Also, I have a people walking out of a good movie story: My dad was a film historian and also wrote movie reviews. The Last Temptation of Christ had just come out. It was only showing in a handful of theaters in the country. We drove up to Chicago to see it. There was a crowd of Christians protesting outside behind a barrier and there was a metal detector and bag search, which was totally unprecedented. While watching the movie, every so often some Christian would get angry and storm out.

I was only 11 at the time (my parents had no idea what was an appropriate movie for a child), so I didn't remember the movie at all when I re-watched it as an adult. But it's not like Scorsese is a bad filmmaker, so of course it was a good movie.

I watched several people leave during Team America. Yeah, it was the sex scenes.

I saw Ecks vs Sever in theatre, and I wish I had walked out.

My mom and I walked out of Jurassic Park 3 and into Artificial Intelligence and we weren't the only ones. To this day, I haven't seen all of either film, but after seeing Jurassic World maybe I was too harsh on JP3. I remember quite liking what I saw of AI. I should rewatch it from the start.

Alien Covenant. After the flute scene I went out, fucking atrocity of a movie. Let's hope the new one is better, now that Scott isn't directing it.

Fitting first example - I once rented Eragon on DVD, and turned it off after at most 15 minutes because it was so bad. Don't think even serving a life sentence I could become bored enough to reconsider watching that...

Batman and Robin.

First movie I walked out of, about the time they were driving around on the rooftops. Abysmal.

Ad Astra - Good potential, abysmal execution

What even was the plot of that movie, I watched it years later on DVD and it seemed like several movies in one and none of them had bugger all to do with each other. Nice VFX mind.

Chappie. And I was one of the people leaving early.

The oryginal Suicide Squad.

Phenomenon (1996) with John Travolta.

We were with a group and some of the group wanted to see it, despite doubts by some of us. So we went anyways, figured even if it's bad, it's a shared experience. The movie was kinda meh, boring and forgettable, but not bad per se. However it is a looooooong movie, after about an hour about half of the group wanted to leave. Multiple people had already walked out of the theater at that point. By the time 90 minutes rolled around even the people who really wanted to see the movie said they wanted to leave. We were one of the last to leave, most people had walked out at that point. The theater apologized and gave everyone a voucher for another movie.

It wasn't even the good kind of bad where it turns into campy or corny or anything like that. It was just boring AF and maybe more of a TV movie than an actual theater experience.

I didn't see this in the theater, but if I had...

Showgirls. It was kind of a big deal when it was new because there was so much nudity and one of the stars had been in a very wholesome sitcom as a young actor. I was young enough that even though I'd heard it was awful I kinda wanted to see all that nudity, I thought how bad could it be? It was so terrible. So very terrible. The nudity couldn't begin to make up for how terrible it was.
