I'm going to skip out on a movie date.
Why would you want to skip out on the date?
I don't want to be seen in public with someone who will make the experience bad.
That is a mean thing for you to do. It's good to honor the promises you made to someone. If you promised to go on a date you should go. If you want to cancel it, let them know and reschedule it at a later time.
It's not a promise and I don't care about this. I don't like to be seen with this person.
If you don't like the person. Why did you agree on a date?
