Unfortunate phrasing

The email address associated with my Netflix account just got an email about the new movie "United 93". The email starts out thus:

As someone who enjoyed 9/11, we thought you'd like to know United 93 opens Friday, April 28th in a theater near you.

So. Enjoyed 9/11. Hm...

Of course, the 9/11 they're referring to is the documentary filmed by two French filmmakers who were doing a documentary about a rookie NYC fireman and ended up filming the events of September 11, 2001. Netflix knows I "enoyed 9/11" because I rated the movie on their site.
