For the last 10+ years, I've been collecting a list of any movie mentioned on reddit or HN as being good or excellent. I also will add the Netflix top 100 DVDs each month (yes, I'm still a DVD Netflix subscriber!). I'll also add all of the academy award nominated movies (although most of those already show up in the Netflix 100).
That list has grown to about 650 movies now (fun fact, Netflix will only let your queue be 500 movies per profile).
They are all stored in my Netflix queue, so I can't share the list.
My first task is figuring out a better way to maintain the list outside of Netflix, and a way to export the Netflix list to the new method, as well as having it auto-import some top films lists automatically.
If anyone has any suggestions on what to use to keep track of the list or any easily importable "top movies" lists, I'd love to hear them!
