I don't like movies where horses fall down. Especially when a horse falls down a cliff and kinda bounces, like in a movie we watched last week.
Also, I don't like movies where someone is chained up around their wrist or their ankle, and the bad guy gives them something sharp and leaves them alone. It makes me think about what I would do if a bad person chained me up around the ankle or wrist and gave me a sharp object and left me alone. ... I don't like to think about that.
Movies that I do like are scary but there is no blood. Just ghosts and maybe a witch or skeleton.
Psychological thrillers are always a lot of fun. The popcorn just disappears during psychological thrillers. And then you wonder, "Hey! Who took my popcorn?!!" What a mystery...
