My reason is I can't stand the reluctant hero trope. Where, for example, a grouchy misanthropic isolated farmer is the ONLY person who can pilot this spaceship and save humanity, so he does it but grumbles the whole time. I don't remember exactly what interstellar's version of this was, but that's where I bailed. No disrespect to anyone who likes it. I'm pretty picky. There are a lot of really common tropes that I avoid and I abandon movies all the time.
