Hi Fanfou2! Welcome to OC.net, and may God bless you and guide you on your journey to the Orthodox faith. I am on that same journey, as an ex-Roman Catholic who at long last was blessed with the opportunity to began attending the Coptic Orthodox Church a few months ago.
I must say, I was similarly shocked when I found out about the existence of so-called Charismatic Catholic groups. Luckily, without realizing it at the time I had been baptized into a relatively traditional Roman Catholic parish. It still used the Novus Ordo, but I had never even heard of Charismatic Catholic movements until I moved to another state and began attending a local church that seemed open to such deviations (without being a "Charismatic Catholic" community, thankfully). When I found out about the Charismatics, I immediately went to see my priest for some sort of explanation. He said that they are mainly a development of the 1960s-70s era changes in the modes of worship deemed acceptable in the Western Church, and that he personally doesn't really understand why they're acceptable, either. When I asked him then about some of the, eh...not normative practices in the parish he was currently in, he said he didn't like them either, but the senior priest saw them as a boon to attracting and keeping the youth (this was in a college town).
I'm still not really sure what to think. I preferred then, and suspect I would prefer now, more traditional worship, though I am glad that I do not have to worry about this specific problem in the Coptic church (the Coptic Church has its own problems, particularly in the lands of immigration, but they are not of the same type as the RC charismatics, nor do they receive the sanction that those groups have received from the RC).
