Dear Brother Lewis, just some thoughts to add to the mix.
1 Co 10:23 All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not.
1 Co 10:26 For the earth is the Lord's, and the fulness thereof.
Now the following is not the context of watching movies, but the total of our Christian walk can be affected by our and other’s conscience. We are a light to others; good or bad.
1Co 10:28 But if any man say unto you, This is offered in sacrifice unto idols, eat not for his sake that shewed it, and for conscience sake: for the earth is the Lord's, and the fulness thereof:
1Co 10:29 Conscience, I say, not thine own, but of the other: for why is my liberty judged of another man's conscience?
1 Co 4:3 But with me it is a very small thing that I should be judged of you, or of man's judgment: yea, I judge not mine own self.
1 Co 4:4 For I know nothing by myself; yet am I not hereby justified: but he that judgeth me is the Lord.
1 Co 4:5 Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.
