This is a short post to address what Blüdhaven is. Part 6 has more superhero comics references than I'm comfortable with, especially considering that I'm not into that genre, but it was a time when I gave them a chance because you can't make jokes about them if you haven't even read them.
Blüdhaven is a city in the DC universe that is often depicted as being near Gotham City where Batman lives. Since Gotham is usually associated with New York City (some argue otherwise, but I can't be bothered to get into a debate), that makes Blüdhaven something like New Jersey. There are plenty of websites that attempt to piece together the fictional geography to real world locations and this seems to be one of the more popular theories.
The more important question here that you probably want to know is whether my opinion on superhero comics has changed, right? Well, it is safe to say that the answer is a resounding...
