Based on Zod being in the film, Kryptonite absolutely has to be used. I'm sorry but Kryptonians are immortal, infinitely powerful and basically unstoppable by any other means. they don't need to eat or sleep, They only get tired until the utmost conditions. Kryptonite is the only leveler these beings have. That is unless you want humans running around firing red sun lasers.
