Netflix can be a bit shit, but it's worth it if you invest the time to create a decent profile and add things to 'Your List' that you've previously watched and enjoyed, so that the algorithm can work its magic and make relevant suggestions for you.
I love it when people ask for these types of recommendations - I've spent 5 out of the last 12 months in hospital, so have watched (and have had recommended to me) hundreds of hours of Netflix! It's obviously hugely subjective, otherwise no one would have to ask because we’d all be watching the same thing, but hopefully you'll find a few gems in amongst all these replies - I've spotted a few I quite fancy giving a go myself!
I watched 'The Platform' recently, good if you fancy something a bit different – a completely original idea as far as I know and well made. Spanish, but dubbed.
'Kidnapping Stella' is really well done. German, with some decent acting.
'Isn't it Romantic' was a really fun movie, with a pretty original take (ironically!) on an old format. Light-hearted, starring Rebel Wilson.
I saw 'Marriage Story', which has great reviews and award nominations. I found it a little slow, but I suspect you need to be in the right 'mood' for it.
'Downsizing' is a good movie - the concept is fantastic, I felt they could have done more with it, but it's still a decent watch.
'Blackfish' is a documentary about killer whales in captivity; surprisingly watchable and a heap more interesting than expected.
A couple of other films I've enjoyed recently, while not available on Netflix, can be found on other websites; 'The Hunt' and the remake of 'The Invisible Man'.
Natascha Kampusch: The Whole Story is a dramatization of the real-life abduction of a 10 year old and her 8 year captivity.
I know you asked for films, but a couple of series if you fancied them: The 'Black Mirror' episodes are compulsive, incredibly dystopian and quite unnerving in places. I really enjoyed 'The Umbrella Academy', which is based on a comic about a family of superheroes. Not my usual thing, but thoroughly entertaining. The whole family enjoyed 'The Good Place' and my top recommendation at the moment is 'Money Heist'; bloody brilliant, another Spanish one. 'Orange is the New Black' is also an excellent watch (except the last season, which is kind of slow). Finally, if you haven't seen it; 'Breaking Bad' is my all-time favourite show, ever. Cannot recommend it enough!
There are also loads of documentaries available. Lots of prison stuff and some in-depth 'investigation'-type series ('Making A Murderer', 'The Staircase', 'The Trials of Gabriel Hernandez'). All (I think) of Louis Theroux's documentaries are available on there if you like his stuff.
