I understand that this could be quite subjective but I find that I can’t watch through the first 15 minutes of most modern horror films, as they’re either so bad or so predictable that you can guess the outcome of the film before you’ve finished it.
I’m a tradtionalist when it comes to this genre; I still like Blair Witch Project even though nothing much happens, but to tell the truth it’s films like that that so many others learnt from and built on. The original Alien film was made on that premise… in that you don’t really see the namesake.
There are some films that have followed this particular trait. The Hills Have Eyes 2006 remake was redone following the success of others (Texas Chainsaw, Amityville Horror) and is great as you don’t see any of the action until later on.
The original Texas Chainsaw (1974) is great for the same reason. The cinematography in that film is off the chart.
I’m not a fan of jump scares, and films that constantly build up from one scene to the next just to create that reaction. They tend to not have any plot either and for that reason they tend to be quite boring.
I’m open to suggestions though and happy to receive any recommendations!
