The plot is every bit as zany and far more elaborate than that of Face/Off, but here again, you just go along with the silliness to savor the performances.
New York Times:
En route to this cynical fade-out, Conspiracy Theory does show off enough glossy style ... and incidental cleverness to keep viewers largely hooked.
Los Angeles Times:
In the hands of stars in denial about their stardom and a director who can't be bothered to take things seriously, it has come out implausible and unsatisfying, a comic thriller that is not especially funny or thrilling.
Globe and Mail:
...more long-winded than cunningly elaborate, more simplistic than elegantly simple, and more nonsensical than anything else.
Unfortunately, the parts of the movie that are truly good are buried beneath the deadening layers of thriller cliches and an unconvincing love story.
...listening to Gibson's Jerry try to communicate what he's been through isn't suspenseful; it's exhausting.
Minneapolis Star Tribune:
Donner directs with an efficient hand. He keeps the action moving briskly. But most important for this format, he knows how to slip in a quick joke or two without detracting from the tension of the suspenseful plot.
