3. Lava Fight
The Moment: Obi Wan meets Anakin on the fiery, volcanic world of Mustafar. The two have a climatic showdown until Anakin is eventually beaten and left to die next to the river of molten lava where he is consumed in flames, yet somehow survives.
Why it's Dumb: This scene is cartoonish in it's use of lava as a danger that will only hurt you if you physically touch it. Molten lava is what happens when rocks underground are so hot they actually melt, reaching incredible temperatures of 700-1,200°C. However Anakin and Obi Wan feel perfectly safe frolicking right up close, in one scene even standing on floating rocks within the river. In reality they both would have burned to death in seconds. Most incredulously Anakin actually makes physical contact with the lava and somehow survives when he should have been vaporized.
