I felt similar after half of e1. The later twists and turns got me to the end of e1. After e3-e4 I'm giving it a solid 6.5/10. I have a feeling I might watch again taking it to a 7/10. As a semi-binge it's working well for me. I'd put this easily equal to Firefly although Firefly was not sci-fi/horror and this definitely is - including the classic horror 'look behind you! look behind you!' moments.
Perhaps I'll give it another go then :) But honestly even though Firefly took a couple of episodes to "find its feet" there was always a spark, something to like... I just couldn't find anything (like at all) to like in what I watched of this.
