Wendigo!

I watched a documentary, it was quite good and haunted me.
Have you ever heard of Wendigo?
Wendigo : An unusual creature from Yukon myths, half phantom, half beast, embodying the dangers of Winter in the flesh. An elemental spirit of the wind and cold, it moves through the woods with preternatural stealth and speed, leaving hauntingly scorched trails of distantly spaced footprints in the snow.
It's attributed various powers, including flight, invisibility, the projection of illusions, and a keen tracking sense for its prey - typically unwary travellers, especially young and foolhardy ones.

The most common origin for a Wendigo is the consumption of human flesh during a harsh winter; this awakens a feral hunger that gradually transforms one into the monster. Intentional association with fell powers ('bad medicine') can also achieve the same result.

It was scary but I felt excited when I learned about them. I hope someone here will like it.
If you know a good movie about scary animals like this, dont forget to share them with me, I will appreciate it.
