The Truman Show 9/10
Another one of those "What is reality?" movies. Maybe even one of the first ones.
What if your "friends" aren't your friends but actors and everything you do is according to a script. Closely watched by millions of people.
Now you can break that up to two parts.
First part
"...everything you do is according to a script.". This means that there is no such thing as luck and the whole concept of
"We accidentally bumped into each other". Everything that happens around you is planned, step by step.
And
"Closely watched....". Every action you take is watched by someone else to see if you break any rules. Meaning that you don't have any privacy.
This can also be linked to the recent trapwire network.
The movie is similar to The Matrix, Bioshock* and Metal Gear Solid 2: Sons of Library.
Bioshock* The movie also touches on the idea of creating your own Utopia. A perfect world without flaws.
