If your trailer...

1. Makes me cringe
2. Fails to make me laugh
3. Fails to move me or interest me
4. Includes mentions of anything I've come to despise
5. Contains spoilers, either in regards to plot, theme or allegory
6. is basically a full synopsis that reveals most of the movie or leaves me able to guess the ending.

I won't watch your movie.  Think about how you want to present this film and don't give me some overstuffed or underwhelming trailer that will fail to make me interested. It's not hard to create a trailer that covers all the bases without ruining half the movie or giving me tonnes of jokes. Oh and don't give me ten seconds of test footage and call that a trailer too, NETFLIX. You're not even trying anymore.
