Started the Magicians, deviates from the book pretty early. Everyone looks 25 but is supposed to be in college. We shall see how it goes, the books had the most annoying characters in many ways, but had a really solid ending.
The Expanse also deviates a lot, and seems to be moving a lot slower than the books in many ways. But I just started the books so who knows.
Spiral seems interesting, but not sure it is quite the French Wire as it was described to me.
