Overrated directors, in my mind :
-Coppola : Yeah, I loved the godfather. It has been my first cinematic shock. Apocalypse now has good scenes, but it's not a masterpiece. Apart from that, Coppola made no interesting movies, and yet, is said to be the ultimate boss.
-Woody Allen : keeps repeating the same movie, over, over, over and over again. Rich folks, beautiful women with instable minds provoke havoc in a traditional structure.
-Almodovar : Long movies dealing with what he thinks is "drama"... Generally, normal human behaviour, and it's not interesting enough to make movies about it.
-Gus Van Sant : because it's long and with no dialogs doesn't mean it's deep. It's just long and without dialogues. Made a few great movies, though, but I still can't forget Elephant and Last Days.
-Lars von Trier : Empty and pretentious filmography, with nothing to say. Good cinematography, though, some shots are beautiful, but the movie is still empty.
-Paul W.S Anderson : Resident Evil. Nuff said. Imagine "The Last of Us" made by this guy, with Ellie doing matrix flips and ninja clickers.
-Ridley Scott : sorry, sorry. 90% of his movies are masterpieces, and the man has proven himself a genius. But it comes a time when you have to quit. When you hire Lost's writer for Promotheus, Green Lantern's writer for Blade Runner's remake, when you actively attack the ones actually reviving your own franchise and when you start to make Robin Hood and Exodus, maybe it's time to quit. Leave the audience with good memories.
I also find Lord of War way, way overrated. Alright, the director also made Gattaca, which is a masterpiece indeed, but I found Lord of War awkwardly written, strangely shot and badly cast.
On the other hand, there are directors who'd deserve way, way more recognition. I think about Tarsem Singh (The fall), Joe Wright (Atonement, Annah), Nicolas Winding Refn (Pusher, Drive etc.) and Tomas Alfredson (Let the right one in).
