Not a theater walkout, but... We just tried to watch "Legend" with Tom Cruise, Mia Sara, Tim Curry, and directed by Ridley Scott. It was so jarring, shockingly bad we couldn't last past the 15 minute mark. The writing, the acting, the direction, the music (with bombastic synth stabs), and really terrible editorial/audio fx choices. Also, there is so many feathers just floating around. Honestly, I love b-movie fantasies (Krulletc) but this thing takes itself so seriously and is so cringingly bad we just couldn't get through it.

Didn't walk out, but wish I had: the first Wonder Woman movie with Gal Gadot. They managed to make a Wonder Woman movie that was more about her boyfriend than Wonder Woman. Wtf.

I know this isn’t going to be popular but I walked out of Inglorious Bastards. I felt like it was so boring and the long bits of dialog just seemed to drag on forever.

Honey with Jessica alba. Like 6 of us walked out and got our money back

I saw Young Einstein on opening weekend...for some reason. No one left the theater but there were only about 4 of us in there to begin with.

highlander 2. people threw stuff at the screen (university town)...I don't condone it, but i understood it.

The Spirit.

Saw it in theaters and left half way through.

Key and Peeles “Us” was atrocious I tried to stick it out thinking it would get better but.. walked out.

Vanilla Sky (2001) with Tom Cruise.

Absolutely awful movie. That was the only movie I’ve ever walked out on, and I’ve seen some really bad movies.

I saw Epic Movie in theaters and it's the worst movie I've ever seen. Nobody walked out but they should have.

We left 3/4 of the way in of "licorice pizza", we were hoping it would pick up since reviewers said it was good, but it's just so bad.

Not a movie, but when I was dating my wife, our college had "The Fantasticks" musical that came to town. The production was so terrible I would guess that 1/3 of the audience left at intermission. This was a professional traveling group and it had to be obvious to them that so many people didn't return for the second half.

Dr. Doolittle. The Eddie Murphy travesty. Bonus: it was a first date, too. We ended up staying together for almost four years. Shared trauma I guess.

~~Atlas Shrugged,~~ Cloud Atlas, I think the one with Tom Hanks. Thought it might be an interesting movie because of the title and Tom Hanks, but I could tell within the first five minutes it was nothing but propaganda. I saw a couple other people leaving along with me.

I've been to movies so terrible I left!
