A good show or a good movie

  This is a interesting question:  What makes a movie a good movie? A good movie could be a bad movie for others, so in your case how can you get to the point of saying.... I watched a good movie.

In my case...

It´s a good movie if you talk about it later even with the people you watched it.

It's a good movie if you are anxious of recommend it to your friends

It's a good movie or show if you feel. And it's better if you feel negative feelings like anger, rage, fear, injustice.
