Query: This was a waste of time.

Let's keep this simple: promising plot ruined by -Bad acting.Poor and often ignorant dialogue (scripting).Inconsistent plot elements (slow walking zombies, then fast ones, then back to slow).An inhabited island overrun by zombies, yet not a SINGLE boat was available anywhere.Piss poor directing.What else is there left to say?
