What should I do if the cinema meets people with no quality and it is noisy?

I used to meet noisy people when I was watching movies.

I've been discussing the plot of the movie in the back, and it's very loud.

At that time, I asked the other person to keep his voice down, which affected the movie ... and then the other person was quiet for a while.

After a while, we started discussing again and even criticized the film. It's really annoying

After being reminded, I can only sit next to no one and stay away from them.
