There is no biblical rule that requires abstinence from "cinema."

There are, however, biblical principles and commandments that apply to movie going as to many areas of life.

There is much pop culture worldly garbage marketed as entertainment that a Christian ought abstain from.

Is the content geared toward profanity? Blasphemy? Mockery of what is good? Glorification of what is evil?

Is spending the money on it good stewardship?

Is spending the time attending, talking and thinking about the movie good stewardship of time?

One aspect of sanctification will be less tolerance of the profane, more care in spending money, more concern about idleness, less concern about amusing oneself, and more concern about what is true, good and pure.
