One of my favorite movies is The Guest, mainly because it subverts the idea of explaining to the viewer why the situation is the way it is. All of the main character's life events have led him to the point he is at in the beginning of the movie, and there are already concurrent plot threads running by the beginning, but we're never told or given an explanation as to why the situation is in the state it's in, just that this is what is happening, how is our main character going to get out of it, etc.

Another movie with a noteworthy use of subversion is The Thing -- you'd think something, anything will be explained by the end of the movie. Nope, nothing, more astoundingly, the end of the movie sets itself up as if it's preparing for a twist -- you don't even get to see the twist. You just know there is one, and the movie ends.
