This is the type of film that has to be judged in its own terms. It doesn't set out to be groundbreaking or cerebral; it aims are to simply entertain and raise the occasional chuckle. It succeeds in both these aims admirably.
Brian Donlevy is a force of nature as the lead, brash to a fault, but always forgiven for his sometimes excessive zeal. Norman Foster is perfect as the barroom piano player Donlevy takes under his wings as a fledgling underwater engineer.
The female leads, Glenda Farrell and Helen Wood, are both playful and charming, yet stand up to the men when appropriate. The plot machinations may be predictable, but are executed with skill and aplomb.
If you're looking for intellectual stimulation, look elsewhere. But it's a cracking good time you're after, High Tension will fill the bill.
