Worst! It started out great and was seeming quite interesting. Then they added cave men and alien like humans. Went too far into the future. I liked when the guy went out of the tunnel and trees/vines had grown inside the Jeep outside. Would have been good to see the common world maybe 40 years later. But instead they went back inside the cave and moved forward... who knows maybe 5,000 years. Geez too much in a short film.
Either make it about space/aliens or Earth/humans.
