Ok. It's no secret. Derren Brown knows his stuff about playing with our minds. This movie is yet another proof of just that. Mind control, or brainwashing as you might call it is a scary thing, but done the right way it could be quite a lot of entertainment as well. Just as Derren Brown's mind-control movies.
There's many different opinions on mind control. Actually, some dictionaries refer mind control to torture. Some people even thinks mind control is about using drugs to get people to open up. Mind control is being used a lot more than you realize in you life, and most likely you're being exposed to it many times every single day. At home, at work, yeah, just about anywhere you go. Even a simple commercial on TV is a trick to get your mind going, and many times that's actually working quite a lot better than what you might think.
Anyways, as said, doesn't have to be a bad thing. Even if it can be.
