Depends on who you are. The element of surprise is a huge part of works, esp horror or suspense movies. Eliminating the surprise leaves out a big chunk of the experience.
In what way is anybody ever ‘surprised’ by a horror movie's relatable narrative (as opposed to those entirely circumstantial moments that “make you jump” and that — significantly — you cannot really express)?
I'm not sure you'd get it if you haven't experienced it up to this point. Maybe just how your mind works.
I know some people walk into a movie consciously or unconsciously determined to not be surprised. They're usually disappointed to varying degrees or at least not surprised by many things. Best way to experience those movies is mentally go with the illusion for at least the duration of the movie rather than try to outsmart the director. I mean, common tropes you'll see coming anyway but one gets more out of it overall.
