I didn't really find Inland Empire scary. I don't really think it was meant to be really. It was really weird and I guess disturbing. It was an interesting film and the Digital video added to it, but I think Lynch should defo go back to film it looks much better imo
It wasn't an overall scary movie, but there are certain parts that kind of make you jump and leave with this feeling that I can only describe as OH SHIT THAT'S CREEPY. A lot of horror movies (the shittier ones, at least) might make you jump but after that you're fine; those parts in Inland Empire, though, actually sent shivers down my spine! There are only three parts really that did this (that I can remember, at least):
When that one lady appears OUT OF NOWHERE and says "Who is she?", when Laura Dern is running towards the screen in slow motion then all of a sudden everything speeds up and her face has this crazy distorted smile, and near the end when Laura Dern is shooting the polish guy and all of a sudden her crazy smile appears again and fhjus fuck that shit gets me every time. Granted, when you know what's coming that stuff isn't really as scary (except for the last one, seriously that shit is creepy as hell!), but it's still kind of creepy.
Also David Lynch uses sound so well. I really think he should make an actual horror movie one day because it would probably be scary as hell.
