I think it's not bad at all. The added question features are neat and, for what they have to work with, the obstacles and stunts are fairly good. But, the host is very, very robotic. I'm sure they want the hosts to stick to something of a script, but you can do that without sounding like you're reciting lines. Chances he had to improvise just weren't good. Also... why the heck aren't there microphones in the podium? Stagehands having to hold them for the contestants seems pointless and cheap.
My other thought is I know they want to be safe but having the stagehands so heavily involved in the course takes the feel away. The stagehand running the flag over to Gum Drop was like "huh?". Also, some of the obstacles are a bit too far. I know they wanted to go for the scrambled feel of the original course, but when the contestants have to run (or walk, as it would seem) the length of the stage from Gum Drop to Popcorn, it takes some time. This is apparently made up for by making some of the "find the flag" obstacles really easy, but it can improved.
As it stands, I give it a B, a B- on a windy day.
