Although I thought the episode was enjoyable overall, there was quite a few plot holes that took me out from certain moments. How does Superman still have any powers under a red sun? The show has established that his powers won't work at all while exposed to red sun radiation. Didn't one month pass by in the normal world during Superman's trip to Bizarro world? It doesn't seem like Superman was there for more than a few hours. They still haven't fully explained why Ally merging with her bizzaro counterpart is so dangerous. Also, why would someone like her be willing to grant that type of power to anyone else? Seeing that he was a big celebrity on his world, why did Bizarro Superman live in a humble farm in Kansas?
