This show is really the kind of show that should be wrapped up in a miniseries. You can't extend the monster of a week formula out forever with such a small cast - knowing that the main characters won't die takes away the suspense.
One thing that really bothers me is the shots when we actually see the cameraman as we are traversing through the woods. So we're to believe that he's running ahead of the group, placing cameras down, and then running back to film them as they sludge through the jungle? This is the problem with the found footage premise. Why would he have the camera pointing at himself as he was digging for the flower underground? He wouldn't even be able to see. It makes sense on the boat or when they set up camp to have static cameras strategically placed around, but not as they're trying to do life and death escapes.
I'm just having a harder and harder time suspending disbelief as the show goes on. No one has any sense of danger or self-preservation ("hey, can you head up to the navigation room, blind and alone, to get me some string?" or "I know everyone's blind, but I'm going to walk around not saying anything so people can't tell when I sneak up behind them, oh no, I got stabbed") until it's convenient for the plot (when the cameraman says, "whelp, you two are blind and as good as dead, fuck you I'm out").
I'm going to stick with it, because from time to time it does have some genuine suspense and creepy moments, but I'm not going to hold my breath for a satisfying conclusion.
