What are Home theater must-haves?


I’m relatively new to the thread but love scrolling through and seeing all the amazing home theaters people have built. Hopefully in the near future I’ll be able to build my own, when doing so I was just curious what you all thought were must haves that make it “a home theater” rather than just a projector with some chairs. Things such as a dark painted ceiling really make it for me but I didn’t know what other things you all liked!
