Looks like the new corporate model is to release these shows early on the web to create a buzz before the actual TV premiere.
SyFy has realized that their philosophy of airing B movies like Sharknado and imported crap isn't working so they are trying to get back to their SciFi roots with The Expanse, Childhood's End and The Magicians.
Just watched the first 2 episodes. Im not blown away by it, but will continue to watch and see where it goes. Coming off a weekend where ive been watching nothing but star wars i may not be giving this show a fair shake yet
