What do you think is the worst offense a film can make?

And by that I mean what is something that makes you angry in films? For me there are 2 big ones.

- Being Boring.
Sure I can enjoy a film for other reasons but firstly I like to be entertained or amused by a film. Granted many films have slow spots and thats fine if it has other redeeming values but a film that just bores me is a major frustration.

- Bad Messages
A lot of films I have on my worst 100 are ones that have horrible morals or advice to them. Films that were made to take to heart. Films like Gods Not Dead, Loving the Bad Man, Audacity, Cries of the Unborn and War Room just to name a few.
