Christian Charismaticism

The recent movement known often as the Charismatic Movement is a movement which associates with Christianity, and in specific, especially loves to talk about the Holy Spirit.
At it's extreme, those apart of the Charismatic Movement will incorporate many practices in their church services that are different from the average; some people scream, some get hit, some fall over in a claimed convulsion, all in the name of the Holy Spirit, healing, and a profound spiritual experience. Is this Biblical?
In moderation, claimed charismatics often simply believe that the gifts of the Spirit are still active today. Many disagree with this; is it Biblical?
Today, Zach and Michael give their thoughts on the Charismatic Movement and "charismaticism" as a whole, trying to determine what's Biblical, and what isn't.
