I'm rating it a solid 5, because I actually was entertained enough to watch the whole season. That rarely happens with bad shows.
The first two episodes are pretty bad. But the show gets better and better after that, before it starts dropping in quality again at around episode 7 or 8. The last three episodes increased the facepalm-value and ended in a last episode that completely ruined the barely existing like I had going for the show.
Despite some of the other reviews, I found the acting okay overall. With what script they had, all seemed to have done their best. D'Onofrio felt a bit off considering his other performances while Meat Loaf was doing great.
The writing and dialogues seem to depend on the writer and episode. (one example of many: Avan Jogia tells D'Onofrio to not run away from conflicts because they just keep following you. 5 mins. Later in the episode he runs away from the group to avoid conflict...)
The core idea had me watch it, and with a higher production value and proper, consistent writing, it could have been a good show. Not great, but good enough to stay in mind in a positive way. Sadly, the writing is inconsistent. Some episodes work, while most of them don't. Some even negate the progress from the episode that aired just before. I can get over bad CGI if the story is catchy and I'm entertained. Some of the caracters act clever or logical in one episode but completely dumb and cliché in the next one. The whole series jumps in quality and story from episode to episode. Also, while Avan Jogia is supposed to be the main character, he rarely even shows up or gets anything to say in most episodes. The last episode made me lower the score 0,5 points because it completely negated the character development of two people again. Give it a go if you have nothing else to watch. But you definitely won't miss anything if you pass.
