I will now say a few sacrilicious things about the new trailer for David Simon’s “Treme.” First, this doesn’t tell me anything, and it’s loaded with (admittedly amazing-looking) New Orleans cliches. (Jazz funerals! Trombones!) Second, it makes me both miss “True Blood” and wish “True Blood” was better. That aside? If this puts Katrina and New Orleans-the real story of America-back into the “national conversation” again finally, then David Simon deserves a Nobel and an Oscar and an Emmy and maybe a Peabody. Also some award that I will make up and decoupage and mail to him.
