The notion of an undercover agent with an untrustworthy mind is a great gimmick — and on a commercial level, Dying of the Light sometimes plays as just another high-concept vehicle for a comically overacting Mr. Cage. But Mr. Schrader’s vision is strong enough to rage against the hackier calculations.

While its bleak assessment of American intelligence operatives imbues the story with some modicum of topicality, the specifics never keep pace. The movie becomes a bland action-drama lacking the sophistication to deal with its weightier themes. As a promising endeavor hacked to pieces, the movie's fate mirrors its anti-hero's own failed ambition.

Not to say that the movie is a mess. Instead, it plays out as a more or less conventional direct-to-video-style thriller, distinguished by a handful of subtexts and images that might have been developed in a different version, but here register as mere quirks.

It's sort of a fascinating mess, a jagged, dark jumble of a thing anchored by Cage's anguished, moony-eyed obsessiveness. It's not bad enough to be fun, but maybe just bad enough to be intriguing.

The irony is that in the low-key but mildly absorbing “Light,” Cage comes close to making it work.
