This isn't some kind of reboot or remake of Outer Limits, Black Mirror, or the Twilight zone or whatever else..this is something entirely different. It takes elements from these sci-fi shows and weaves it into something entirely different. It feels similar, but it can't hold a candle to those shows individually..and it's not trying to.
It has a large cast of actors and actresses, and weird ass episodes..but it's fantastic. If you like sci-fi shows and want a new story every episode, this might be the show for you. It's almost like a B-Movie or a B-TV show if you think the acting is terrible (I think it's pretty good..but if you're a stickler (insert Rick and Morty reference)..that's on you) It's probably not for you.
With this latest episode (Bob) I cried like a baby. The story they tell every episode is fantastical and I've been waiting for a show like this for a long time since Misfits ended. To be fair to the user critics, episode 3:Chronos wasn't OMFG over the top amazing..but it had emotion to it and it resonates.
Don't let negative reviews detract you from this show, try it out..see how it fits. This is only the first season, think about shows you love and how crappy their first season was. (South Park? Anyone?)
Give this show a fighting chance.
