A lot of Disney movies have had a lot of power over me.
Although I did not care for the most of it, Bambi is a prime example.
But The Lion King, most notably.
It just had such heartwarming emotion; it was literally impossible not to feel anything by watching it.
In terms of being "freaked out" or "disturbed" by a film, probably The Exorcist.
As well as having total control and power over me, it actually affected.
As I keep watching it, it's effect slowly fades away, but there are still some scenes where I literally cannot watch.
Another example would be Kill Bill;Although I was not particularly freaked out or disturbed by this film. But it does have some very overpowering scenes.
'Legends of the Fall' left me pretty depressed. There's probaly alot of other more depressing movies, but my mum probally wouldn't let me watch alot of them.
