Every single comment that proudly declares "my interpretation is obviously the correct one and you other guys are wrong" only further serves to prove what an actual great piece of art this is. That is, it's art that makes you think and can be validly interpreted in many different ways, and more serves as a projection of the own viewer.

Who necessarily cares what the original design of Waterloo Place is for, it's also just a place in the center of London with lots of foot traffic, visibility and a ton of statues. Or that the place Banksy is from threw a statue into the river (that connection in particular is quite the stretch - are you saying all the things that happened in your home town are inherently reflections of you?).

The more I see people declare that their interpretation is "right" (just see the argument thread over whether right wing or left wing people are more likely to wrap themselves up in a flag), the more I think this is a pretty brilliant piece of art.
