Now, I love a bit of good graffiti. My Cousin get's paid to do it, and I've dabbled in the past.
That said, this stuff is, quite bluntly, ****. Not to mention wildly out of place. I would see a point (albeit, not a fantastic one), if he'd sprayed a decent Mural reflecting the area, history or similar, but even well done "traditional" graffiti would look wrong here.
