A24 is on a roll. Their latest movie- Green Knight is getting excellent reviews. I can't think of any other independent studio that's been producing so much great stuff.
Basically, when you see a trailer and the A24 logo in the front, you know you're in for something brilliant, original and sometimes harrowing.
Their movies have won a load of Academy awards in recent years and garnered immense acclaim.
I think an argument can easily be made that they are probably the studio churning out the most consistently critically acclaimed movies in the last 5 years or so.
