Yeah, unfortunately the prosperity preachers are all about what is "showy" and "spectacular" and the immature tend to be the loudest and most ostentatious speakers of tongues. I do tend to think some of them embellish or overact to make it sound more interesting and spectacular. So I end up feeling super uncomfortable around them and it gets so chaotic that I can't even quietly concentrate on speaking in tongues. This is really the main reason why I avoid those types of churches.
Plus the manifestation like holy laughter, being slain in the Spirit, being drunk in the Spirit, acting like an animal, and the other stuff you mentioned are NOT IN THE BIBLE and are not from the Holy Spirit. The moment I see anything like that at a church I'm visiting, I don't even wait for the worship or service to be over. I am OUT OF THERE!
As to the naive and young Christian, I received the gift of speaking n tongues when I was young. I have to say, if a person really does belong to God, they will learn how to use the gifts properly sooner or later and they do get better at it with time and experience, becoming more orderly, and not given over to overacting. So, I'm pretty patient with those who are new or young to it. Also, it never hurts to pray for these younger brothers and sisters in Christ, that they get better at it. And sometimes, you have to find an opportune time to just tell them directly about any improvements and corrections they should consider about it.
Oh and you mentioned about being "taken over' - where people lose control and do weird stuff?? I don't see that anywhere in the Bible so I'm thinking it's not of the Holy Spirit? It has never happened to me.
If anyone else who has the gifts know of a verse where a Christian is "taken over" please point that out to me. I've witnessed a person coming to ask for prayer one time at my old church and she was just acting so weird - like she was possessed.... well we all realized she WAS possessed but she was asking to be prayed for. But the pastor was very stern with her and told her that she needed to repent in order to receive healing. It was pretty clear that they had tried to minister to her before but she wasn't letting go of whatever sin she was holding on to that caused her to be possessed by a demon. It was pretty shocking! But I learned something very important that day - that there is a good reason why God wants you to submit to the Holy Spirit at all times - not only for growing more godly in Christ, but submitting to the Holy Spirit keeps you from being possessed by demons.....
