The 4K format has a habit of exposing cheap CGI. Luckily, Piranha 3D uses CGI sparingly and wisely, mostly for the swarming fish and wide destruction shots. The close-up attacks? All real puppets, real gore, and real screaming extras. That practical foundation looks better in 4K, not worse.
On the surface, Piranha 3D seems like an odd choice for a premium format. But think again. Aja directs with the confidence of someone who loves schlock but respects craft. The famous “underwater opening” homage to Jaws ? It looks stunning. The fully practical gore set-pieces? They’re art. The cameos—Richard Dreyfuss (yes, that Richard Dreyfuss), Christopher Lloyd, Eli Roth, and a legendary turn by Ving Rhames as a deputy using a jet boat propeller as a weapon—are all rendered in gorgeous, ridiculous detail.
This is the one bittersweet note. The 4K Blu-ray disc itself is 2D only. Most home 3D formats are dead, so that’s no surprise. However, if you still own a 3D TV and a compatible Blu-ray player, the included standard Blu-ray 3D disc (in some combo packs) remains the only way to experience the film as intended—with fish fins jutting out of your screen. The 4K version trades depth for sheer, razor-sharp detail. It’s a fair trade.
