Soylent Green (1973)

This story takes place in the bleak future of 2022 but it feels very much like 1973. There are some moments of inspiration but a number of tricks have been missed in imagining a dystopian future, notably race, gender and technology. I know that dystopia is supposed to be worse but it looks rather like 1973 instead of an degraded 2022. The story is good but almost everything else is dated. As such, it seems it may benefit from a remake but I think the reason it hasn't been remade is probably because it has actually be rebooted a number of times in other films and its actually a fairly simple plot.
