So... I rode this attraction for the first time today. I had obviously read detailed descriptions, but I had avoided ride videos.
Overall, I think it's a great addition to the park. The meat of the ride (the 360 tunnel) was just okay, but everything on either side of it was fantastic. Loved the queue (the scareactor got me!), loved the first scene and the reveal of the wall and the gates, and I was floored by the Kong AA; you can really tell that last scene was kind of Universal's way of saying to some of the older fans, "We know you miss Kongfrontation, so we're going to give you a little something special at the end here," and it was wonderful. Kong may be the best AA I've ever seen, and I was very impressed with the complete experience of the ride.
