This sounds like a pretty awesome panel. The recap here is worth a read. Landis, Gunn, Darick Robertson and Grant Morrison.
waitaminnit...Landis is arguing that Chronicle isn't a superhero movie???? Are you kidding me? It fully is...and it's a great one at that. Is he gonna claim World War Z isn't about zombies?(oops wait, that's Max Brooks...well, the points the same.)
