Movies take a lot of work.
Especially horror movies. I mean have you seen the work that goes into putting one person into that horrific makeup and costume. Thankfully now a days there is a thing called computer generated effects but that was not true in the old days.
Even now a days, directors like to use practical effects rather than cgi and seeing Freddy Kruger or Jason not terrorizing people is a weird thing. Did you ever think you would see Freddy Kruger just chilling with the kids? No? Well, now you can.
You’ll see everyone through a different perspective from now on.
