Thee Gamma

Im late to the party with this review. But can someone tell me why anyone thought it would be a good idea to put regular ppl against magical beings. Like why of all the villains they could’ve chosen did they fight a super powerful sorceress and her brother, which has been disintegrating everything he touches but for some reason decides to backhand two ppl at once instead of just disintegrate them, and they win? Riddle me this, what in the holy plot armor was that Batman?
