I think Shannon managed to portray the madness, obsessiveness, lack of hope, and vulnerability of this Zod really well. If they wanted a more straightforward villain, I feel like Shannon would steal the movie from Cavill.
If this is one of the weaker performances by Shannon, it's a testament to how awesome Shannon is as an actor, overall.
