Apologies if this is best suited for "Movies & TV", but the plot elements of the movie seem to fit "Fantasy" pretty well.
This movie was available to stream on Netflix a few years ago.
It was a low budget indie film that revolved around the premise of the struggle between light and darkness (almost literally).
The good guys of the story are "angels" of sorts who behave similar to a pixie-style balls of light when travelling, but otherwise take on a human form.
The bad guys are manifestations of shadows and darkness. I vaguely remember them having an Agent Smith style appearance, but their glasses/faces were made of white noise.
The movie had a heavy focus on free-running / hand-to-hand combat.
The main protagonist/antagonist (whose name I think is the title of the movie) is a troll-like creature who wears reaper-esque robes and hides his face. His task is to abduct this little girl and deliver her to white noise bad guys.
The conclusion of the movie involves the robed creature turning on his masters and choosing to save the little girl. In the end it is revealed that
he is actually the little girl's single father who was transformed into this creature because of his guilt (or something) involving a traumatic experience (likely involving the mother).
