Stupidity: When Clark is fighting Evil Superman in the junkyard, Evil Superman looks up and sees a huge magnet directly over Clark and Clark notices it too. Evil Superman uses his heat vision on the chain causing it to heat up then break dropping the magnet on Clark. Clark had plenty of time to get out of the way before the chain snapped but he just stands there when it finally falls on him.
Suggested correction: Isn't it implied that the junkyard battle is all in Superman's head? "Clark" acts timid, indecisive, and overall strange during the scene because the scene is the manifestation of his identity crisis, and we all sometimes act in ways that make no real-world sense in dreams.
Plot hole: Gus could not know that Superman was in Smallville in order to give him the fake Kryptonite.
Suggested correction: It's pretty clear the town made a big deal of Superman's visit. There was a parade, a brass band, and the Mayor gave him the key to the city in front of a sizable crowd. It's not unreasonable to think Gus and Webster learned ahead of time, especially considering Webster ran an operation there.
