All the reviews seem pretty bad but I actually really liked it. To each their own I suppose. At first I thought it was going to be a Lost remake or something but it pleasantly surprised me. The writing wasn't the best but the actors were so phenomenal that you rarely notice. The only thing that disappointed me was the ending. I wish they could have some how saved the big reveal for another season or something but I guess they are trying to get people drawn in. Overall, I'd say it's definitely worth the watch and I'd really like to see the part two of this.
P.S. as someone that has lived in Houston Texas, the geography of the whole thing kinda doesn't make sense. There's zero way you can see the city of Houston from Galveston... That's all.
