The constitutionality of judicial review isn't determined by the degree of contest from other branches of government, but from the powers delegated by the Constitution. If your argument is that any power usurped by the government that isn't contested by that same government is the law of the land, then you're no longer discussing a constitutional state.
To bring this back on topic, I think that the zany antics displayed in Wickard v. Filburn, and the near complete absence of a check on that sort of topsy-turvy decision, pretty clearly demonstrate that the Supreme Court is not really suited to handle judicial review.
The public discussion of judicial review is pretty sparse, partly because it's been around for so long that most people genuinely think that it's an enumerated power (an easily corrected mistake that is pretty pathetic in its own right), but that doesn't mean that the process is universally accepted. Of course the government, which is benefitting greatly by not being bound by a constitution, isn't debating the validity of the process. They get to claim the validity of being a constitutional state while simultaneously acting free from any well defined constitutional rules. What's to complain about?
