Nobody is wrong, nor is anybody right. Film is subjective, after all.
Do you actually think that by posting idiotic comments like this you're going to either hurt my feelings (clearly your intention) or convince other people that this interesting and unique list is in any way inferior to the generic blockbuster-filled crap lists of many other film goers?
Don't bet on it.
I could say the same thing to you about your love for Christopher Nolan, who I see merely as a relatively talented commercial filmmaker, not as a "great artist," and certainly not someone worthy of the kinds of hyperbolic statements made. Paul Thomas Anderson is certainly a candidate, and some would claim Wes Anderson as well. Joel Coen is another. As for "this" generation, David Lynch is still very relevant and one of the best alive and working today. You may not care for these directors' work, but their style and sensibilities are their own, distinct, and something that sets their work apart from the more mundane, workmanlike stuff of people like Nolan. Regardless or your opinion of them, their films are very well liked, so it's entirely possible that they WILL eventually be known as some of the best American directors of their generation. Nolan's films are just plain/derivative in comparison. Any director could have made the films he has made, and they would have been at least passable. There is little distinctive about his work, although he's very good at what he does. Everybody has their own list of best movies. The point is, few critically acclaimed movies don't make great directors. Witness Nolan.
Then again, this is just my OPINION, which is not founded on proof or certainty.
