Yes i have to say..tribal warriors.Did we not get enough of this in doomsday, And many other films who rely on this future ide that the human race will go back to the B.C era...Hummm The rest of the ideas for the show sound good and could make for a interesting film..Get rid of the tribal idea,nd put a cool looking alien race that Finds the ship, And Makes it there home, trying themselves to get back to there planet.Much better...Brad
