The fact that the only natural Kryptonite we see in L&C is the teeny bit embedded in Clark's capsule (in the first Tempus episode, I think) and another lump from Smallville, suggests that someone on the show thought this one through, and avoided the Meteor Rocks / Mutants nonsense from the Smallville show.
Yes, some of it is nonsensical. It was also a decent plot device for "Smallville" to let Clark have some villains to conquer and problems to deal with. Otherwise the show would be boring.
What I find unbelievable (or at least it makes it hard for me to suspend my disbelief) is
how much kryptonite there is in the Smallville universe. Tons must have fallen down! And considering that it's thought that a tiny little meteorite caused the
Tunguska event why didn't all the kryptonite that fell in the Smallville area cause an equivalent or greater amount of destruction?
More ignoring of the laws of physics. Par for the course in TV-land.
But hey, this is a show about a guy that flies. So maybe I should just lighten up.
(Or, as my co-worker says, "Does anal-retentive have a hyphen?")
