Is this a Worst Directors list or directors who have "lost it"(As in don't have the spark they used to anymore) list since you're using "Broken"?
Either way I'll do my "lost it" list since you pretty much covered the worst directors already.
- Steven Spielberg
He's one of my favorite directors, but everything he's made as of late just hasn't been that great, the last movies I watched of his that I though were good were The Terminal and War of the Worlds and I did have some fun with Kingdom of the Crystal Skull and Real Steel, but everything he's been involved with these days just don't have that same fun creative spark of such amazing movies like Jurassic Park, Back to the Future or the original Indiana Jones trilogy.
I still think he's a fantastic director I'm still looking forward to his Halo TV Series though and I hope he gets as creative as he was back in good old days again.
- James Cameron
My number 1 movie director and soon to be fellow countryman James Cameron created 2 of my all time favorite movies EVER, Terminator 2 and Aliens, not to mention the masterpieces known as Titanic, Terminator 1, True Lies and The Abyss.
But Avatar just didn't feel like he was the same director of those masterpieces of the 80s & 90s, Cameron's massive leap from actual props, jumping road bikes and trucks into sewers and such into a movie that was 90% CG was just wrong and also didn't have Cameron's flare from his 80s & 90s movies. Now he's gonna be wasting the rest of the decade on Avatar sequels which will be the first time he's directed more than 2 movies in the same franchise, but if Terminator 2 and Aliens proved anything, it's that Cameron knows how to surpass the original, I just hope that part of him didn't stay in the past.
- Paul Verhoeven
The director of the timeless classics that are getting garbage PG-13 Remakes Paul Verhoeven made some damn awesome movies, my favorites being Robocop, Starship Troopers and Total Recall. But since he abandoned western films after Hollow Man he hasn't made anything really good.
