I saw the premier with a group of friends and I thought it was okay!
There were several awkward exposition dumps and I was not happy with Lash (costume or CGI) and Fitz's role in the episode was silly at best. Didn't like the suitcase scene at all.
But I liked Quake a lot (amazing how she's the most interesting character of the show for me when she used to be the most boring) and the two other Inhumans were enjoyable on screen.
I have high hopes after the amazing Season 2, but I'm not dying for more. Then again Season 2 didn't click with me how awesome it was until much later, so I'll keep an open mind!
Also really looking forward to seeing what's going on with Simmons!! That's exciting!!!
