A disconcertingly large portion of that review is based around speculating about what people were thinking, and assumptions about studio machinations. There's a whole mess of assumptions here, and I'm not sure some of them really have that much to do with the film, or ring true. A few that caught my eye:
I don't usually hear "groundbreaking," but I definitely hear innovative, because it is. Sure, we've seen films about dreams before, and we've seen films that question the nature of reality, but many of them are wishy-washy, or only skim the surface of the idea, or treat it as some bizarre oddity we're just meant to accept. That's all well and good, but it's not quite the same thing as Inception.
But really, whether or not a film is groundbreaking or innovative is of secondary concern here. I realize that any time a film attempts to be thoughtful some fanboys, or teenagers, or whatever, flip out and declare it the deepest and most poignant thing they've ever seen. But just as bad is the rush of corresponding reviews which seemed less concerned with the film itself, and more concerned with offsetting a perceived overenthusiasm for it. "It's not as good as this particular group of people think" isn't the same as "It's not good."
I don't think so; the film wants us to think the scheme inside it is complicated, and it absolutely is.
Of course? When did this become some kind of established fact?
Really, if marketing had half the sway here that you seem to be suggesting, do you think they'd really have cast Marrion Cotillard? Do you think the relatively normal moviegoers that you seem to dislike so much know who she is, or find her to be a draw?
Let's consider the possibility that this is the story Nolan wanted to tell. Because we have every indication that it is. Nolan's gotten to make some pretty atypical films with some pretty large budgets, and there's no denying that he has a lot of pull when it comes to marketing, but his films consistently give far, far less away in their trailers and clips than basically every other major release.
Cobb remarks that she's picking things up unusually fast. That's a perfectly reasonable thing, given that she was recommended for the job by Cobb's father (in-law?) because she's an exceptional student. She gets to see more of Cobb because she's in a unique position; he has to tutor her in this art, and he doesn't have much time. She's also very bold; she violates Cobb's trust a bit to learn his secrets, he doesn't just offer them up.
Also, since when is being young and child-like something which undermines creativity? It's exactly the opposite.
The "action" is in their minds. He doesn't have to be gruff/strong/whatever.
I've re-read this paragraph three times, and I have no idea how not showing us what happens with the top in any way breaks the film's "rules."
Also, to my memory it doesn't wobble and stand-up straight. It just starts to wobble. But that's probably not important in regards to this point, anyway.
Simply pointing out that the music is urgent (how is it "stock" exactly?), or that the editing is quick, isn't an indictment in and of itself. You can't say "Michael Bay uses quick shots, Inception has quick shots, ergo Inception is as bad as a Michael Bay film." Sometimes, they're appropriate. For example, when you have a ton of things happening on four different layers of reality at once.
Also, I'm pretty sure that some of the shots in Ariadne's tutorial are held for quite awhile at some points, precisely to "enjoy the beauty of the mise en scene."
I don't think he has, and I see almost nothing to suggest that he has, but more importantly, I don't know why anyone would be so concerned and inherently put off by a film simply because they think it was trying to appeal to a large audience.
