The show certainly can pump out the drama. The music especially: it just hits in a way, that you expect there is something wild going on. Some operator work also tries to add to the atmosphere, but... In the end it feels like those old TV novellas I saw as a kid, I think they were advertised as Brazilian, but not sure if all of them were.
The plot is extremely simplistic. Think low budget "Mafia: The City Of Lost Heaven". And with very little logic. I mean, if you look at the story as a whole - yes, there is some level of logic to it. The kind that you see in Hallmark Christmas (or generally "romantic") movies. They do even suggest some "paranormal" at some point. Or at least there is a bit that may be interpreted as such.
The main problem is that this should have been a movie. I see potential, especially, since the 1st episode started with comments about bad phone battery, and they tried to utilize those comments only in the last episode, where it did kind of work. Not ideal, but still.
If they went with approach similar to Statham's "Crank" from 2006 but more emotional, or recent "Mercy Road" but with more people - it could have been great. They do have fast dynamics after all, it's just that all the unnecessary and stupid fluff (which is "talked about", not so much "shown") just ruins it.
But we have what we have, and as is... It's not good. Soundtrack is still the best thing about it, and perhaps they should release is as a digital album.
