If this is on anyone's lists of favourite episodes, I will be extremely surprised. This episode simply could not do anything that 'Pirates of the Caribbean' has done better. In addition, the whole wave (excuse the pun) of pirate mania in recent times has largely subsided. Due to the limitations of simple filming practicalities, the episode was shot while the ship used as the location was in dock in calm water, absolutely killing the swashbuckling atmosphere and therefore feels completely lifeless. In addition, the pirates don't actually do any pirating. They have their loot and just want to go home. Rory is killed again and comes back to life, which is by this time just getting tiresome and predictable. The Doctor is also exceptionally erratic, changing his theories on the 'Siren' every 5 seconds, making it hard to keep up with what is contradicted. But the biggest problem is how sloppily the episode was put together. I am of course talking about the pirate who disappears without explanation half way through the episode. Obviously the siren took him but it's only by the end of the episode and the fact the matter wasn't explained otherwise that you are left to draw this conclusion. Similar criticisms can be leveled at 'Journey to the Centre of the TARDIS', also written by Stephen Thompson.
