I have Netflix for four screens, plus Ultra HD (4K) and that costs £9-99 per month.
I also have Amazon Prime, and Sky, inc movies, but find Netflix far better for films.
There have been many times that a film hasn't been on Sky, or available at an extra charge on Amazon, but is sitting there on Netflix, just waiting to be watched!
Netflix is also great for watching when we go on hols to cottages in this country.
As long as there's a decent internet connection and speed we always have something good to watch when we're collapsed after a long day of adventuring!
I've just started watching 'The Good Place' (thanks to hildajennij) and am hooked!
