El hombre del saco

I use a horror template that always promises success, mix it with the hip coming-of-age elements and go full throttle on jump scares. How can I still make a mess of the whole thing? Ok, I don't want to exaggerate. How do I make a merely average film out of the good source material? I'm borrowing too much from the Stranger Things concept without making my own. The choice of children doesn't make much of a difference, there's a lack of charisma for the most part. The synthy sound is mediocre and doesn't match the ambitions that the film sells in its marketing. I realise somewhere in the middle of my journey that I don't actually want to make a real horror film after all. What do I want then, I don't know, because generally there's a lack of big ideas? And scary, let alone horror. But hey, the pacing is right and the film only takes 90 minutes to watch.
