Links to Blackfish Documentary-style film are as follows:
Blackfish is a documentary about a killer whale that is "pushed to the limits" by mankind and so seeks an ultimate revenge.
To watch the film Blackfish online and for free, you can currently find it at https://freevideo.me/movies/2490060-blackfish-2013.html
However, due to the fact that it is probably not hosted there legally (I'm not 100% sure about that, just guessing), I wouldn't be surprised if the video was taken down soon - so watch it before it disappears.
I hope you enjoy the movie Blackfish.
After I watched it, I really wanted to learn more about marine biology and how we can help animals and humans live together in harmony. I know it sounds a bit cheesy, but the movie is inspiring!
