Yeah the flashing images were kind of weird....
The "movie" if you can call it that, was in itself very stupid....
Basically, if anyone will claim that they got stuck, its not because of the movie, and you didnt get stuck...
Before the movie if you kept telling to yourself "this will work" or "I will get stuck", when the movie ended your mind basically was telling not to get up, because you believed so hard it works.....
If you were just sitting relaxed there I very doubt it did....
The crying part; well my eyes started watering, but not because I wanted to cry, but because I stared at the TV screen. And I guess you know what happens when you look into one point for a long time without blinking. Yes, you start crying.
