While it borrows some plot points from Train to Busan (2016 South Korean film), Blood Red Sky does have good character development and proficient acting among the primary actors. Much of the more gruesome violence is dimly lit, but sound effects and the soundtrack effectively explains what may not be shown. As with many movies, bad decisions are made to advance the plot. However beyond yelling at my screen, I was not taken out of the film. There is a resolution, a definitive end which is a nice change from many recent films. Not every film has to provide new IP or a mid-credit scene. A movie as a single thing of imagination can illustrate what may happen when prejudice, stupidity and viral infections collide.
