It's not a problem with the acting, the concept or the special effects.. The huge problem is how incredibly stupid all the characters actually are, and the frustratingly idiotic mistakes they make along the way. This show keeps you cringing at their stupidity most of the time, every single episode, multiple times.
Do NOT expect a show in which the storytelling and script was clever and kept you in the edge of your seat. It is not that.
That said, most people are going to get hooked with the show (because that's how people are), also because the plot and lore isn't terrible, so I know there's a Season 2 coming... I just hope they get clever writers to work on it.
I'm not exaggerating my review. Actually, this is the first time I review a show and I took the time to do so because I had to vent somewhere. Don't believe me? Watch it. You'll be fast forwarding the last two episodes, as I did, just to see the ending (which btw was boring, stupid and predictable).
