Sorry for the confusion folks, I rode again this AM and I was again seated in row 6. I now know understand my confusion better. The hole is pitch black and I didn't notice the screen was missing for the front car does a good job of blocking the view of the hole, since it is so dark in the next room, I just perceived the hole as the front car blocking my view of the screen, really, if you are looking where the scene is trying to direct you to look, I doubt many will even notice there should be a screen there. I can't say what it looks like in rows 1-3, but from my two rides in row 6, I really did not notice. I do think the fog was better timed/lasted longer, but it is also possible I felt this way for you no longer see the screen moving.
But the heat it certainly on time now which was not the case back in Sept and there is now at least a little bit of water splashing on you where again that was not the case in Sept.
