1) An Education
Jenny's life is forever changed when she meets a man twice her age and becomes his girlfriend. This is a fantastic movie with great performances by Carey Mulligan and Peter Sarsgaard.
2) Lawn Dogs
This is a film that I first saw on Lifetime (ha!) I was about the same age as the girl in it at the time. I found it strangely fascinating and if anything, it helped me identify shady behavior a little more easily. This is a story of a 10 year old girl (Misha Barton) who strikes up a friendship with a 20 something lawn boy (Sam Rockwell) in her jaded gated community. Don't worry, he's not the creep in this film.
3) 5 to 7
I originally had a more disturbing pick for this one but I changed it last minute as I really don't think I could ever watch that again. 5 to 7 is a film of Anton Yelchin's that I missed when he was still alive, and didn't see until after he tragically passed. I wish I had seen it sooner because now it's one of my favorite performances. Brian and Arielle meet by chance one day, and strike up an affair with the rules being they can only meet between 5:00 pm and 7:00 pm .
