I think it's you being grown more than anything. Kids are dependent on others for survival so it's easy to be scared. (*rant begins*)
If you want an adult to be scared you gotta immerse them in the narrative, make them feel like they're physically there, then start either slowly or suddenly stripping the main character(s) of their faculties. No gun no phone no technology... that's another thing.
...Technology is making entertainment obsolete to an extent. It's hard to sell nikkas on tension if they know they'd be able to tweet their location or call 911 in the moment.
Same thing applies across genres. Movie villains in action movies are becoming trash. I was thinking of this the other week. Let's take S.H.I.E.L.D. vs. Hydra, (which was later jacked by G.I. Joe vs Cobra). Both sides of the conflict had impossible technology by 60's - 80's standards. We didn't start getting cellphones and video games until 70's. fast forward and cats walk around with apple watches and smartphones tweeting bullshyt, that's two different audiences. The old tricks are like shooting blanks. That's lowkey why they had to base the new Joker movie in the 80s. Cause it's hard to sell the idea of one nikka in a clown suit doin the most cause in 2018 we know the police been shot this nikka. Especially black folks lmao. Y'all clappin nikkas left and right but you got this cac in clown makeup runnin the streets?
