Sometimes a willing suspension of disbelief can mean the difference between a tense excitement and weary eye rolls. Blue Thunder, a helicopter thriller starring Roy Scheider, isn't very realistic or plausible, yet if you're willing to take it with a grain of salt, you're in for a real treat. Unlike many unbelievable action thrillers, suspending disbelief here does not mean foregoing the use of one's brain in experiencing the film. If anything, the surveillance power of the helicopter nicknamed Blue Thunder engages the brain, presenting it with alluring and frightening possibilities. Fast-paced and gripping, this the ticket for adventure film fans.
