Greyhound is diverting, though it takes significant liberties with historical accuracy. Tom Hanks portrays a destroyer’s captain confronting German submarines. He comes across as brave, devout, unassuming, and he contends with numerous u-boats seemingly determined to attack him. The opposing forces taunt him, arrange naval engagements reminiscent of older warfare tactics, and remain on the surface, openly tracking his convoy—a rather blatant display. However, a dose of reality is needed here. U-boats didn’t engage destroyers in the kind of direct confrontations depicted; they avoided detection and did not seem to relish their duties. This movie presents an invented scenario that feels quite absurd. A u-boat would never have stood a chance against a destroyer and prioritized evasion above all else. The United States, at the beginning of the war, was significantly inferior to u-boat groups. It required considerable time before they began protecting commercial vessels. American naval leaders largely disregarded suggestions and assistance from their more knowledgeable British allies, which naturally exacerbated the situation. They eventually improved but only after enduring substantial casualties. Essentially, this is a work of fiction. It’s enjoyable, features strong performances, I appreciate Tom Hanks' presence, and while often unrealistic, the action sequences are well-executed and fast-paced. By all means watch Greyhound for simple enjoyment, but don’t anticipate anything like "Das Boot." Even Das Boot wasn't entirely accurate, but it was considerably closer to reality than this film could possibly be. 6/10
