First the bad.
They're stuck in the wilderness in 10,000 BC and they're clothes are immaculate every episode not a spot of dirt anywhere.
The overall acting is sub par and the plot lines are extremely predictable.
How many things can go wrong in one place from wolves, storms and other native tribes.
Now the good.
All I can say is if you watch it for what it is (a low budget time travel series) and take it with a pinch of salt it's worth a watch in small doses.
