Only time I ever walked out of a film was at a festival and the film we chose to see just because we didn't have anything else to do. It was just a shitty low budget horror film. So no nothing I paid directly to see, I do my best to not see bad movies in the theater.
I saw probably 75-100 in the theater last year (not counting stuff at film festivals) and the only ones I would say without a doubt are bad are Suicide Squad, Alice Through the Looking Glass and The BFG (also saw Hands of Stone, Train to Busan, and Coming Through the Rye in a theater but all were at festivals and all were bad)
