And here I thought I would be one of the lone voices in the wilderness suggesting Nolan's Insomnia had any merit whatsoever. In some ways, filmmakers outside of the US have a lovely luxury these days - it takes clout here for any type of ambiguity to seep its way into a movie. But make a film for the European market, and they sneer at a pat ending which doesn't leave open huge questions.

For Nolan, this film is a bridge, proving he could work within the bounds of the studio system and keep big-name stars under control. The fact Pacino gave a performance, instead of phoning in bombast as he does these days, says volumes. Without it, he would not have the personal capital to invest into Batman Begins, which in turn gave him the ability to make projects like The Prestige and Inception.

And... were it not for Nolan's Insomnia, would there be a Criterion edition of the original? Sometimes just bringing attention to the original is a great gift.
