I REALLY loved the premise of Experiment 10, but I'd like to see it taken to a further extreme. The isolation chambers, people shouting in your face etc, would be a LOT more effective if they could just spend more time 'working' on you. I know in the real world this isn't exactly plausible and they need to try and maximise throughput and that, but yeah, I'd like to see that.
Also, a Jaws sort of thing? The ride still scares me and I think a walk through on a boat could work REALLY well. With something like, you know that scene in Free Willy where he's in the underwater viewing tank and the lightning flashes and you just SEE the whale and it's creepy as ****? Yeah, imagine that, but with sharks. Maybe even a cage-diving simulation? I don't know exactly how you'd do it, but it could be awesome.
