'Batman Vs. Superman' Casts Lex and Alfred. Um? What?

Here we have it folks. In Batman Vs. Superman The role of the Smartest Evil Genius in the DC world will be portrayed by: Jesse Eisenberg. Yep that dude is going to be Lex Luther. Wow this just keep getting better. This just seems like crazy poor casting. I really don't get it. Oh and Alfred is going to be played by Jeremy Irons which I am fine with.
