For me, it depends on the movie. I'm glad I saw Mad Max: Fury Road on the big screen - it grabbed, and didn't let go until the credits. And the audio is a big component of that (at home, I just have regular headphones).
But for 90% of dramas, comedies, etc.? The 4K TV in the living room will do just fine.
