I'm writing this review after seeing just the first episode but as far as episodes go, this was more than just a pilot.
The series seems to benefit from solid writing, the pacing is perfect to keep you wondering.
Maybe the "666" in the name comes off slightly cheesy and tries too much to push the viewers towards the Faust tale but the setup is still great. The pilot steadily leads to a number of questions and possibilities all while creating a dense atmosphere that manages to clearly convey the feeling of being trapped in a game led by one man (or the devil).
Sure, the script may resemble the setup from "Devil's Advocate". Being a series however, it can afford letting some things under question. While in Devil's Advocate we had a character clearly setup as The Devil, plain and simple, here we are left wondering what's going on: is there a cult gone rogue? Is it the devil? It is a messenger or some kind of demon?
As far as the pilot goes, I was surprised to see that even if one were to summarize it, one couldn't very well simply give away spoilers because there aren't any to give. Who's who? Who wants what? Who does what? These are questions left to be answered.
Shortcomings? Sure, we could name a few. Aside from a few main characters, the cast is questionable. Perhaps they just need time to grow but I can still think of many debutants in series that have done way better jobs.
The camera was chaotic at times without any real reason.
Final word? The story is catchy, dense and full of suspense. It has the prospects of giving a fair amount of chills if properly developed and I am definitely going to follow it.
It's not entirely a 10/10, maybe more like 8/10, but I'm stepping it up as the recent releases have been incredibly low, such as the cheap teen flick Revolution which can make anything else look amazing.
