If you look at a title like Bird Box, it’s Rated R. It’s all very weird and somewhat confusing.
Sometimes Netflix rolls with the type of system that TV uses for all of its originals, movies included.
It could have to do with festival distribution, theatrical releases and purchased films versus films produced in house, but the average person using Netflix probably wouldn’t know anything about that.
So, if you look at a title like Chevy Chase and Richard Dreyfuss’ The Last Laugh, you’ll see it listed as something like TV-MA.
