Acting was good but they could have polished this gem a little better. That's said I still recommend it, lately anything on the topic of space, aliens, time travel, multiple dimensions has become a favorite of mine and this series actually rails along a true concept. The CERN collider hasnt documented creating mini black holes but that doesn't mean it hasn't happened and aliens exist unless of course one is still limited in belief to the constraints to the constructs that be. Man has made other men Gods since the pretty much the beginning, if you ask me the bible is the first documented contact of alien life. I like that shows like this have become popular, society needs to be comfortable before they hit us with the truth because it will rattle religion and politics.
