The constant knowing irony comes across as somewhat conceited at times, but at least mostly isn't too crass. It's a very funny film, from prat-falls and sight-gags to subtle adjacencies and associations. There are some very meaningful themes and allegories layered so carefully through the parody, cynicism and kitsch indulgence as not to offend the delicate sensibilities of modern arts-cinema audiences.
I overheard somebody say on the way out “that was very Canadian”, but they were talking in a very Canadian way, so I suspect some degree of national pride. It certainly wasn't very Hollywood, the closest there would be David Lynch, and he's just not that subtle.
