I've seen many a child scared by Haunted Mansion, which isn't nearly as "evil" as BBoBH...
Personally, I think it looks good. I hope they did something with the main queue room, because that was- by far- the most inhospitible queue in the park... in my opinion. And yes, I'm counting Firehawk. That USE YOUR FRIGHT LIGHTS TO SCARE OFF THE GHOSTS!!!!! spiel combined with the DUN DUN DUN... DUNDUNDUNDUNdundunDUN! music that absolutely blasted every few minutes gave me a guaranteed headache every time I waited in line. So far, it looks like BBoBH is actually an upgrade from SDatHC.. so far.
