I finished the 8th episode yesterday and I pretty much liked it so far.
I also played Fallout 1, 3, New Vegas and even 4 to a degree.
Especially the foreshadowing to the second season got me hyped a bit.
Finally they starting to take video game adaptations seriously.
Cannot say that episodes were to slow or something like that.
It was rather welcomed that not in each and every scene something has to happen as it is common in nowadays productions.
Either someone has to give exposition and talks all the time or action happens...any other than that seems to be wasted time and not entertaining enough.
But Fallout dont give all that much exposition. It throws you into that story without much info on the essentials.
So If you had no contact to the games so far it could be a bit hard to get into this.
