I'm one of the rare comic fans of the Inhumans and I'm gonna stay optimistic but watching that trailer you can't help but think it was probably best that Marvel made it a movie instead. The set and costume design looks bland and human-like, when one of the big things about them is that they're really nothing like humans at all. Attilan is wacky as hell and given Guardians 1 and 2 as well as the Thor 3 trailer, the movies are nailing that look and style completely. This visually is looking like AoS with a slightly bigger budget. Hopefully it comes out and proves everybody wrong, but we'll see.
At least Lockjaw looks good, no doubt we'll see him only a handful of times during the series though.
