10 Major Plot Holes You Probably Missed

6. Superman 2

The Hole: Forget Me Not

By the end of the second film, somehow - and very conveniently - Superman has the ability to extract specific memories from Lois Lane via the medium of a kiss, which wipes her memory of the fact that Clark Kent is Supes. In itself, this is a little hard to take, since it's a little difficult to believe that Superman's lips could work with the precision of a neurosurgeon to cut away one specific strand of memory without removing anything else?

How come Lois didn't all of a sudden forget how to drive, or who her third grade math teacher was? Okay, okay, he's Superman, he can do what he wants, but that's just not a substantial enough answer to legitimately deal with the question. Where does this ability come from exactly?

To go for almost the entirety of two films suggesting that the preservation of the Clark Kent alter-ego is crucial to the protection of Superman, and then to suddenly just establish that he can wipe people's memories by kissing them seems like a fairly major departure.

Yes, it would have been an entirely different film if Clark Kent had spent a good portion of it kissing anyone who had worked out his hidden identity, but if he had the power why keep it so quiet for so long?

Definitely doesn't spoil the film though - which succeeds despite the huge potential problem of being the knitted-together work of two separate directors.
