Although it would be good to see some changes, I kind of doubt we will, the attraction was a runaway success last year and I think they'll probably take a 'not broke don't fix it' stance.
I wouldn't really agree that it needs any more peril or fear written into the storyline, but then I am a wuss

.
Personally I liked the Wolfboy section, and thought the Venom section was good, when we went through the kids certainly seemed to find it fun.
Also -
they could at least replace one of the many identical pictures in that section with a drop panel!
I'm almost 100% certain at least one of those WAS a drop panel, as it frightened the life out of me...
