I have found very different Charismatics than the rest of you it seems.
Yes, sometimes these people will hold their hands up in parying, or speak in tongues, but it is not mimicing someone else. They are not trying to blur the lines between us and them either, nor are they simply trying to get emotional highs.
Many in the Charismatic movement look to the spirituality of St. Francis of Assisi, or St. Therese of Lisuex (sp?) or other mystics.
That is the description of the vast majority of Charismatics I have met.
There are some who seem to want to focus more on emotion and less on “rules” and some are nearly schismatic, but the movement as a whole is legitimate. They believe the same things we do, they just express it differently.

p.s.- I have no idea if it is effective, and I certainly believe it is not a response to evangelicals. Ask a Charismatic Catholic (who is in line with Church teaching, there are cafeteria charismatics too) if they do the things they do to convert evangelicals, and they will say no. They do it because that is how they worship, and how they believe they should worship.
