It's been a terrible year for franchise movies (save for Wonder Woman, Logan, and the MCU, ironically enough after all the shouts of "superhero fatigue").
But in terms of non-superhero fare? We have seen as bonafide hits that are also really great smaller gems like Get Out, It (as you mentioned), Split, Baby Driver, and even carryover hits from last December like La La Land and Hidden Figures. Plus for big movies that are great and did great business, we had Dunkirk.
Actually, I think 2017 is shaping up to be a great year for movies. The ones that are turning it into a Box office drag that flopped almost* all sucked. (Pirates 5, Transformers 5, The Mummy, King Arthur, and whatever else I'm forgetting).
*It's a shame War for the Planet of the Apes underperformed as it was really well done. And on a "small movie" note, I am saddened that Detroit flopped, because that movie was an intense pressure cooker that should be seen.
