I liked previews more when they didn't spoil the entire movie. Movie theaters are okay for louder movies. I regret watching a quiet place in a theater. The loud audience did their best to ruin the experience.

Some theaters charge a little more and have a one-warning policy before ejecting customers for talking or using cellphones. I watched A Quiet Place in such a theater and thoroughly enjoyed the experience - the high-quality surround sound was great for a movie that relies so much on sound design.
