So far it's just bad
Decided to check this show out but so far it's a whole lot of terrible writing, Even worse animal CGI effects and sub par acting or maybe it just seems that way because of the piss poor writing. and why is the guy so concerned about the damn drugs. Who's he gonna sell them to. Cave men. Are seasons 2 and 3 any improvement?.
Also it wasn't just people that fell through that sinkhole. There's cars, a plane or 2, a Big bus and a huge road sign. And all the scientists in the present have unearthed is a tiny ring on a necklace and a note in a bottle. Really.
