I'd watch a Blizzard made movie about Overwatch that was just cinematics like this. I would. They are really, really good at this stuff.
This video is designed to get people onboard with the new Overwatch open beta that starts this week. I recommend taking part because I think Overwatch is pretty great.
But yeah, I feel like Blizzard has really been pushing the boundaries on its cinematic work with Overwatch. I legit want feature or episode length stuff like this.
