I think it is one of Christopher Nolan’s greatest till now. But it is not going to be that popular. Some will hate it because it is too expository, shallow, cliche-yish and the posturing with ideas. Some will hate it because Nolan disappointed them in their idea of fun. It has the same fate that looms over all the artists who try to make ‘popular art’- they will not completely satisfy anyone but none can dismiss them either.
And please don’t drag Tarkovsky in here. That is obscene. If you want, let’s talk about 2001: A space odyssey. The difference is obscurity and the awe that it offers. But Nolan doesn’t have that privilege. Nor the guts. Because he has a billion dollar fan base to please.
