Archipelago: my most uninspiring movie of 2011, which is a shame because it's the one film I looked forward to seeing and most wanted to like. I live where Archipelago was filmed, and ultimately thought "what a wasted opportunity".
The Scillies are a unique part of the British Isles, and a film made here should leverage the location in some way to drive the plot, give a sense of place, or set a mood. Archipelago did none of these things, and could have been filmed at any other coastal or rural setting without changing the feel.
