23. Meet the Spartans (IMDb: 2.8)

In ancient Sparta, King Leonidas and his ragtag group of 13 warriors (plus cameos and parodies) face off against the Persian army led by the god-king Xerxes in a crude spoof of 300, packed with pop culture references, celebrity jabs, and lowbrow gags.
This parody is universally trashed for lazy, dated humor relying on fart jokes, product placements, and endless unfunny references to movies like Transformers and High School Musical. Acting is over-the-top amateurish, effects cheap, and the script feels like a rushed SNL sketch stretched thin. It earned a spot on worst-films lists for being offensive, repetitive, and devoid of wit—yet its “so bad it’s good” camp has a small following for ironic viewing. Critics called it a bottom-of-the-barrel waste, but it still edges out many disasters in user votes due to sheer absurdity.
