We've all seen these TV programs about cinema in which they review some recent movie and then go over the filmography of its director or its main actor by showing a few clips from previous movies.
Well, "Fear Itself" is 90 minutes of just that: a selection of clips from horror movies of different sub-genres, with a narrator speaking about things like what fear is and what things we are afraid of. It doesn't sound too bad, does it? The thing is: quite frankly, she doesn't say anything interesting, the script is trite and her dull and monotonous way of speaking doesn't make things better. It feels like someone had the idea but then couldn't come up with a good text.
The clips themselves are short and generally not from the climatic parts of the movies. There's nothing frightening there, and even less when all the scenes are shown completely out of context. In many cases you can't even guess what the movies are really about. But some look good and might make you want to watch the movie. Don't expect any jump scares or cliffhangers, the documentary doesn't spoil the scenes themselves, but it DOES show the ending of a couple of movies ("Brazil", "Gravity").
In the end I got curious about a few of the movies and now I would like to watch them, so if I have to say something positive about this documentary, it is that. But don't expect anything else.
