They almost all do, but that's only part of it. Hollywood is facing a perfect storm of converging trends which all keep people out of theaters. (1) As you point out, their product mostly sucks. (2) Many people have large TVs with great sound systems. Why pay for a movie in a theater that you can see at your home theater in six months? (3) People are used to doing their shopping while staying at home, and they like it. Amazon, & etc., have made us lazy. Why bother going to some unpleasant mall, fighting traffic and looking for a parking place, when you can stay at home and be just as entertained. (4) The popcorn at theaters tastes lousy, unlike the days when it tasted good. The nachos and whatever else they sell are better and cheaper at the 7/11, if you want to eat junk. If you're going to eat bad food, why not stay at home and order a pizza from Dominoes; it's cheaper and better.
I don't want to be entirely negative, so I'll say there are some recent movies that I have liked: Sicario (Ahora, van a conocer a dios), Queen of Katwe, and The Lost City of Z, with the best version of Ravel's Daphnis and Chloe #2, you will ever hear.
