The problem with a lot of these kinds of movements is that they tend to create a selfish kind of Christian who is most interested in what God can do for them rather than what they can do for the kingdom. The churches that sprout from these movements tend to be churches where the congregants go to seek out the fire of the holy spirit. But when you look at the fruits of these individuals at the end of the day; when you ask what their contribution to the kingdom has been, you find out that they spent so much time seeking out the feel good aspects of spirituality and just one more touch of fresh fire, that they simply forgot that God put them on Earth for a reason, and it wasn't to go to church and get all emotional.

Revival is a good thing if it spurs on action. If a revival fires you up to finally go talk about God to those coworkers God has been prodding you about, then it is good. If the revival fires you up to finally take that mantle of missions that God had asked you to take years ago, then it is good. If a revival fires you up to finally overcome your fears and give everything up to go to seminary like God has been telling you, then it's good. If a revival fires you up to fix your broken relationship with God, then it is good. If a revival fires you up to finally step up and volunteer to do that job the church has been looking for volunteers for, then it is good. The problem is that most of the time, these revivals don't fire people up to do any of the above. Typically, these revivals fire people up to go to church and seek out more of the holy spirit for themselves instead. If all the revival fired you up for was to continue being selfish, then the revival was worthless; you may as well have kept to your regular church without a revival; at least then you'd be doing nothing while knowing that there's something missing instead of going out and seeking this emotionalism under the false belief that you are finally doing things right.
