Best of all, if you enjoy Code 8, it recently got a sequel in Code 8: Part II that released directly on Netflix back in February of this year. The Amell brothers both return to reprise their roles from the first movie as well. So if you like the original, you have the continuation already available to see where the story goes next.
Check out Code 8 for yourself via Netflix to see how the Amell brothers compare to what you may remember of them from their DC days. They do say that necessity leads to creativity. So sometimes it can be fun to look to smaller budget movies to see what they are able to accomplish when they have to rely so much more heavily on their ideas than tons of special effects.
