"Even the greatest director can make a bad movie," that quote is true, but sometimes either the director's name is that popular, or it is just that much of a disbelief that that one person can find work. Let's use two examples of opposite ends of the spectrum, with one in the middle: Zack Synder has directed a number of films, starting with a remake of Dawn of the Dead that might've been panned but wasn't, and same goes for any of his other movies that have received popular or praisement, with only one exception and that was Sucker Punch. The other end is M. Night Shyamalan with two successes, and the rest are either negativally reviewed or panned, and yet finds work. The one I chose for the middle is Bryan Singer, who has done Usual Suspects, X-Men, X2, and currently X-Men: Days of Future Past; but, his current track record has been mixed, starting with Superman Returns, Valkyrie, and Jack and the Giant Killer, making me cautious of him directing what might be a hit film, but I've been wrong before. The point is, as the topic is asking: at what point does a director's track-record make him a cautious/negative choice to film a movie? Your thoughts?
