As long as the result of the carnage is good, then not at all.
A&D has done some of their finest design work when put under insane time pressures (see 2012's House of Horrors.) It also tends to give them much more freedom than they typically enjoy (which is why we got the "duck down" tunnel that's now become a staple.)
I wouldn't mind marketing being knocked down a peg, either. This is the game you play when you deal with other peoples' properties. I knew Scream's handlers were ridiculous after Murdy's dealings with Scream 4 in Hollywood... but man.
