That's weird. I don't recall having any problems keeping up. What specifically?
I'm notoriously dumb when it comes to keeping up with TV shows and movies but the whole backstory with Coop and his wife, the Vault 4 stuff with the human experiments, Hawthorne, the Vault 31 mystery, Vault Tech, who the **** is Maldova and why does her name keep popping up, how did the Ghoul find the brothers that knew her whereabouts, wtf is the NCR? I played the games and I don't remember, the Shady Sands bomb etc. I guess I need to keep watching and stuff will be revealed. There's just a bit too much going on when episodes 1-5 were extremely simple.
