good movies not recently released?

Im going onto netflix so if you arent for sure if its instant stream
name a few movies........ Im feeling depressing movies, something like
"worlds greatest dad" or anything that questions society or takes you
through a questioning state, like "the big lebowski".

Maybe anything like that, Ive seen alot of funny genres and action
looking for somthing new and to relax and think about when im going to
sleep. Any help would be appreciated!
