Lots of great films listed here.
I'm a little surprised no one mentioned
The Day the Earth Stood Still. Yes, it is 55 years old, but still worth the trip. If you haven't seen it, I'm sure you can find it on Netflix, or whatever service you choose.
My last blog post,
"Well, if it isn't Mr. Burned-Out Cinder" was on it, though my post a spoiler if you haven't seen it.
