The author seems to go back and forth on his opinion; he states that not every artistic aspect of Chelsea is good, in fact, many are downright awful.  He compares one bad Chelsea day to “a season in hell.”  Then, he writes that every city has bad shows and art.  It is unclear about his opinion on Chelsea in comparison to other cities around the world.  Does he like Chelsea better?  Does he consider London, Berlin, and Los Angeles artistically superior to Chelsea?
