What Say You?

I saw these along the way on my train ride from the airport to Paris. I mean ALL along the way. Some say it's ugly. Some say it's cool. Some say it's rage. Some say it's expression. Some say it's trashy. Some say it's creativity. Some say it's illegal. Some say it's alright. Some say it's vandalism. Some say it's art.

What say you? 

And even this.
