33. Dungeons & Dragons (IMDb: 3.7)

Thieves Ridley and Snails team up with a mage and a warrior to stop an evil mage from stealing a powerful scepter that could control dragons and conquer the world, in a fantasy adventure full of magic and betrayal.
This adaptation is panned for its cheap effects, wooden acting, nonsensical plot, and tone that swings from serious to campy. Script is clichéd, pacing slow, and it fails to capture the game’s spirit. It’s seen as a early-2000s fantasy flop that killed interest in D&D films until later reboots, best remembered for Irons’ scenery-chewing and unintentional laughs.
