Was a teeny bit disappointed with Clark's final action vs the bad guy, thought he'd find a more clever way to solve the problem.
That's very canon and in-character. That's how he's always solved the Zod problem - in comics and movies. Spoilers coming:
[sblock]Superman always executes Zod.
In the movie Superman II he de-powers and then executes Zod in the Fortress of Solitude.

In the comics, he executes him (again in the Fortress) with green Kryptonite. After a speech about being judge, jury, and executioner:
In Man of Steel he executes him physically after being presented with no choice.
Zod's end is always execution by Superman in all mediums.[/sblock]
