Re: Who should be the villain in the sequel for Man of Steel?
It really should be Lex Luthor. He's Superman's greatest, most interesting, most long standing, deepest and most contrasting enemy. He deserves the TDK Joker treatment. The philosophical conflict should take center stage in part 2. It doesn't hurt that Lex Luthor can 'field' things like Parasite, Bizzaro, Metallo even Doomsday as needed, or even be on a quest to access Brainiac.
For the third movie, then you move it to something incredibly physical like Brainaic, Doomsday or Darkseid.
