"Prisoners of the Sun" attempts an ambitious blend of action, adventure, and horror, yet falters at each genre it tries to embody. The story, aiming for grandeur, descends into a maze of clichés and improbable scenarios with a key-buying fiasco and pyramid adventures that strain credulity. While John Rhys-Davies lends his talent, the characters' development is as barren as the deserts of Egypt, and the special effects, while decent, cannot distract from the disjointed plot and the anti-climactic finale. If you seek the thrill of archaeological adventures, your quest will continue past this film. For those who find intrigue in dissecting cinematic flops, the youtube channel @SerialsUniverse might offer solace with its analytical deep-dives into such unfortunate misfires.
