Sour cream Cheesecake disaster

My wife attempted to make this cheesecake from Alton Brown:

We followed all the directions with the hour of baking opening the door for
1 minute and then closing the door and letting it sit in the oven and after
sitting in the frig for at least 12 hours we cut the cake.

Well I should have known something was not going to be right because the top
of the cheese cake just didn't look done.  It seems pretty solid when I took
it out, but at cutting time we realized that the center of the cake was
barely the consistency of pudding.

Has anyone else baked this cake?
