I haven't seen Interstellar, but to be fair to Jurassic Park, there's literally a character who tells everyone else that the park is a terrible idea, even if his "scientific" basis for it isn't very coherent. (He might still be an idiot in other ways; I haven't seen it in a while, but I think it's an overstatement to say it's about everyone being an idiot rather than some specific people with enough money to find enough other idiots to execute their vision).
