I really thought the season one cliffhanger was going to be a breaking news report of "Superman Dead" with Kara watching in horror. It would have been the smart move; it would have finally allowed Kara to truly make her own way, and it would have paved the way for a Reign of the Supermen season introducing us to Cadmus Superboy, the Eradicator, Steel and Cyborg Superman. There would be a full season worth of stories in that.
It was all just sitting there for the producers to grab, and they wasted the opportunity. After how much they've mined the comics material in Flash, I'm surprised and disappointed by their mistake.
