I did not expect to like this fight as I did. A super powered race against a traditionalist warriors wielding magic was a fun brawl. Remember that the Kandorians were reeling from a lost after getting their butts handed to them Gothamites, after Batman laced the rain with kryptonite.
Just look at the surprise on the Kandorian’s collective faces when their powers don’t work on the Amazon’s magic shields. They probably thought they’re being affected by the kryptonite again. Then the cavalry, or flying cavalry rather, just swoops in to provide additional support! And see how the Amazons butchering the Kandorians with no mercy.
