There was Breaking Training Camp, and Goes to Japan. Couldn't find any financial for Training Camp, but Goes to Japan made 14 mil, not bad for the 3rd installment. And again you have to deal with the opening: 1103 theaters, Raiders got 1078. How can that be explained if nobody thought there was an audience for the movie? Answer: it can't, obviously they thought the movie would make bank. Now obviously they didn't realized how much bank since it then expanded to 1778 theaters, but no movie in that era they didn't expect to break 100 mil was going to get an 1100 theater opening, no way.
But JP still runs into the problem of being dumb, it starts right off when they introduce the paleontologist and he tells the kids about the hunting patterns of velocoraptors, I know there's a lot of stuff to be learned from the fossil record but not hunting methods. Right there barely 5 minutes into the movie it is announced that they'll just be making crap up but don't worry because the special effects are gonna be great.
My point was it wasn't a sell out since there was no clear market to sell out to. They opened it wide because of his name. Why not go for the gold? And JP had a bad script. I'm not arguing there. The second half though was what SS does better then anyone. And what he did for nearly 2 hours in WOTW in a different key.
