Its not brilliant, its not even great, possibly not even good, but its not terrible.
I sat through 90 or so minutes of it, and I could tell what was going on, things were well lit, back stories were understandable, and it focused on several characters, almost all of which we will see again in subsequent episodes.
So its not the worst pilot I have seen all week.
Cough * discovery * cough
Hell, it even made me want to see the next episode, which is what a pilot is meant to do.
At least it didn't set up the inhumans, kill them all off but one, and then set the rest of the story with Namor the submariner.
