It's terrible. All the survivors appear to have become blind ... and stupid. Chris dives in for a swim from a boat that appears not o be moving. Nick tries to save him, but Chris says he only wants a swim (WTFF!).
Those on board are watching this. Suddenly Nick is face to drowning face with a corpse!
Expand the scene to see a capsized boat with loads of bodies in the water. Nobody has seen this in the fine weather with the boat not moving. Zombies eveywhere!
Come on! We might be punters but were not Johns!
Not really worth any stars when the writers treat the viewers like they are the Walking Dead!
