It was okay. The core of Gus and Jepperd is great, but it gets rougher beyond that. As a huge fan of the comics, I'm not big on a number of the changes. I can live with the show needing to soften a lot of the edges, but you can also see all the executive notes about developing the mystery, making the world very small (ie. direct connections between the characters), etc. It's very much about ticking all the boxes that most every other mainstream sci-fi/fantasy show has had to do post-Lost.
The show also suffers from problems that other recent Netflix shows have, like Shadow and Bone. They feel the need to pack in a lot of moving parts and plotting without giving space for the scenarios and character dynamics to really develop, which means you don't really feel the stakes or ramifications. Things go from Step A to Step D in an instant, so the emotional impact is limited. For instance, nothing about Bear losing control of her group, and thus losing her found-family and friends, lands for me because it happens mere scenes after meeting her. We barely see how she was with them, so it doesn't hurt when the group falls apart. Similarly, it's hard to feel much about the zoo preserve and all the responsibility for all those hybrids when they barely even hint at how Aimee rescued those hybrids, never show any others besides Bobby until the evacuation, etc.
