The Audience Strikes Back: 'Last Jedi's Plunge Is Worst Ever for a Star Wars Pic

I think I'd need to see more data to actually draw a conclusion here. Is this just a Star Wars thing or do other movies released recently perform similarly?

I think it's entirely possible that it's just a general movie industry trend that people who don't see a movie in its first weekend have no desire to go subsequently - maybe because all the good parts are almost immediately spread around the net? Less incentive to go to theater.
