I went to the seminary for my masters and my wife went to the university. We live nearby and are good friends with the pastor who was preaching in chapel that day. We also know the president of the university well. They are all humble and wise individuals. Absolutely not Christian nationalists. It started not really from the sermon, but from a student who got up and described issues he had been dealing with (confession), and then others did the same and the service hasn't ended since.
My wife went to the service last week, but I haven't been able to and, frankly, have been a bit skeptical. It's also not really my scene anymore, but everyone I've spoken with who has been said it's just people singing together and quietly praying. Nothing real crazy or charismatic (in the theology of worship sense). I have greatly appreciated how the leaders have shepherded this movement so far. They've turned down every request from big name preachers, news organizations, and worship leaders who, well meaning or not, risked turning it into something other than a genuine movement.
However, it's turned into something massive and truly beyond much of their control. They have like 20k people descending on a small college town of a few thousand. So, will there be crazies? Yes, just like with any gathering this large. They don't even have enough chapels or sanctuaries in the entire town, so people are just worshipping in the green spaces at the university. We'll see what comes of it. I imagine there will be good and bad, but the bad will be more public and the good will be more in the everyday changes people make in their hearts, minds, and actions. I can just tell you that the way this started and the way the leaders have tried to keep it centered on something real and genuine is the most encouraging part.
I know they're basically saying they're going to wrap up the actual shutting down of the normal university schedule after next week, so that'll be another significant shift.
