I liked it for the most part. It's really unlike anything else currently on TV, and at only 8 episodes, it's not a big waste of time if things turn south.
I thought that they did a good job with making everything feel creepy, and the jungle (is this shot on location?) was sufficiently claustrophobic and dark. I didn't think anything in the first two episodes was necessarily scary, but I did get creeped out a few times. That's good enough for me.
The found footage aspect doesn't make a whole lot of sense, narratively speaking. Why are there hundreds of tiny cameras stuck to every surface and angle of the boat inside and out? lol I know the original boat crew were filming a documentary/reality series, but come on now.
The scene where the mom is asking the black static monster (it looked more like static than smoke XD) where her husband is was just awful. "Tell me, ghost monster, is my husband alive? Cut me twice for yes and once for no." lol
Also, in the first episode they encounter a smoke monster from Lost and trap it in a spirit cocoon, but in the second episode, when faced with the possibility of a second ghost in the jungle, the son is like "That's hard to believe, stop trying to scare me!" Uhhh...you just sealed a ghost in a wooden cocoon and saw your dad walk on water and hold fire in his bare hands. You're really doubting this now?
It's also kinda lame that every time something spooky happens, someone says "Oh! I remember hearing about this once!" and then they go on to explain exactly what's going on. On one hand it takes most of the mystery out of everything, but at the same time, no one is going to lack for answers. I think it's cool that they're solving their own mysteries so quickly, but it's handled in a very clunky manner.
