It's unfortunate that nearly everything that's considered to be entertainment these days has to be suspected as being tainted with immorality. But that's just how it is.
I know that I often have hopes that a film won't have anything objectionable, but more often than not, it does.
I was fortunate to have a little local theatre that for the most part only had family-friendly plays (protestant theatre), that my sons and I volunteered at many years ago (when I was homeschooling), before I converted. I haven't been there for many years now since I converted, but they are still in business.
