I don't know that I'd say that the lack of a DS extended cut is due to anti-DS bias. After all. WB didn't release an extended cut of
Journey 2: The Mysterious Island - and that's one of their most successful films this year. Nor have they ever released extended cuts of the Christopher Nolan Batman films - and every last one of them has been huge for WB. There doesn't seem to be any rhyme or reason as to what films get extended cuts and what don't - but it apparently has nothing to do with whether a film is a big hit or not - or even a flop.
