6. Superman IV: The Quest for Peace (1987)

This takes the Man of Steel into territory so bizarre it's almost brilliant. With a budget seemingly smaller than Clark Kent's lunch money, the special effects are hilariously dated, featuring flying scenes that look more like a school play than a blockbuster. The plot? Superman battles Nuclear Man, a villain with a golden mullet and powers that defy logic. Despite its flaws, the movie's over-the-top earnestness and sheer audacity make it a so-bad- a good treasure.
