Sled Dogs is excellent movie from 2017. I do not watch many movies under the Documentary category, but this was great and now I am bigger fan of movies of this kind. The movies industry, can't really boast with a large number of better Documentary films. What's more, this is definitely the type of movie that you can watch several times and always see something new, interesting. I've been a big fan of such cinema for some time. It's a movie for everyone, I'm sure you'll like it after watching.
