There is plenty they could do, but in a way if anyone who is a non-frequent visitor to the park notices that a piece of theming is there for Fright nights specially, it'l show Saw wasn't done as well as it could have been. They advertised it before it opened as being 'the scariest ride in the world', and in my opinion there just isn't enough to merit that. So if you say there's plenty they can do for Fright Nights with Saw, you're also saying there's more they could have done in the first place with Saw. And that's probably been Saw's biggest downside (that and the pretty shocking reliability ).
