But yes I agree they absolutely are NOT necessary and I think the shows on them became idolatry for me.
Sorry I didn't get back to you very quick. I feel like it's a long process for most people to follow the Lord in this area.
I'll think about sharing my personal history with films because that might be beneficial for some but for me it's difficult.
My view has developed over the the last 7 years or so and it's not like it happened overnight so I don't really want to just put forward the whole "stack" of all the insights that I've gained because I feel like it's overload for the most part.
I will say that I've gorged deeply on films and yet always (since I was a child) felt conviction about it. I'm not sure that most people put themselves inside the movies the way that I do and have what I would call a "filmographic" memory. They "seed" in my mind in a way that nothing else really does and can be coupled with sin in a way that I don't know of anything that really can besides maybe dreaming. I don't want to get into that much other than to say that they compliment MANY sinful states and one might wonder why that is.
I suppose part of me (and this part I'm uncertain about) doesn't want to "ruin" movies for people as they are ruined for me. I guess because I feel like God may operate within them on some level and that is part of a person's walk and I don't want to cheat anyone out of him working in his timing and somehow benefit the enemy in condemnation, etc.
Anyway, this is requiring a bit more out of me than I planned but I encourage you to just keep praying and be mindful about becoming pharasaical or judgemental in any way...for me that is something to guard against because the enemy seems to take to a different tactic.
Look for little openings and use those. It used to irritate me greatly when my parents would ask "what did I watch" and I didn't want to tell them for guilt or because I wanted to keep it private. Maybe try to start a dialogue about a particular show that you are familiar with without encouraging someone in fandom. Fine line really.
So like you mentioned Power rangers. What did you (your son) like about this particular episode? What is your favorite character? Why? Do you see any parallels to biblically moral principles? I personally would couch that last if someone weren't obviously receptive.
The goal would be to stimulate thought instead of someone just "zoning out" or becoming a "zombie" in front of a TV set. Where are they zoning out to?
If they don't want to talk...why not? Pay close attention to any working the Lord is doing in casting it down...sometimes it's really subtle.
Why
does a person want to be private about it?
People are similar with sermons though. "How was the service on sunday?" ...."it was good". "oh, it was an hour long, maybe a few more words on it?" "What did you think of when he talked about this?" It's uh...a challenge sometimes to do that but you can also do it with films in order to make use of the time potentially. These are just suggestions though, I don't know your child and I don't really you know you either. Could be that little of this is useful but pray about it and if I can help further let me know.
I don't know what will work for you or how far God wants you to go. Balance and being choosy with what you watch is a good place to work from. There are a lot of ways that I navigate the psychology of it but it's too much for me to type right now.
It's a hard fight like I said, everyone fights it differently and some things may be totally unnecessary to understand. We don't need to know everything about evil in order to war against it. Some people only need to know that a thing is wrong or is leaning toward idolatry in order to make changes...others want the reasons for turning made exceedingly clear. I think God blesses the former though and the latter is about submission which transcends to every facet of life with our wills and is a MUCH harder fight for me personally.
