Sorry to say I watched to the 5th episode.
This show is so dumb and poorly written. Some of the very noticeable are...
He sees his wife by a rock and KNEW she lost her ring the. In the present 10k yrs later, he finds the rock. It sit on the ground, but he digs down 4 feet to find the ring.
Pilot gets sent down to find survivers, but he is on a secret mission to find another group that went down in Mojave Desert. And that group happens to build a fort, one days walk ffrom the LA group.
Group has been attacked by giant wolves, Saber tooth cat, and a giant sloth walked through the camp and ate all their food. Instead of having guards, building defensive barriers, building weapons... they play softball.
I can see the producers and writers doing a production meeting like a comedy skit. It's bad and nothing jells.
