Justin Theroux on 'Iron Man' vs 'Dark Knight': no comparison

In a recent interview, the writer of 'Iron Man 2' very briefly touched upon what he sees as the differences between 'The Dark Knight' and 'Iron Man'. This defamer.com article seems to want to link up Theroux's comments with Downey's "**** DC comics" statement, but I see the quote more as Theroux's way of saying that although the two films are in the same genre, they are different enough that they don't really merit a direct comparison.
