I'll be completely honest and give my opinion based on the leaked episode I watched:
The show is good, and I see a future for it however:
I feel like i'm watching a lie, they make Kara out to be as good, or sometimes better than superman which is in no way true. What they should have done was have Superman be a mentor to Kara like Tom Cavanagh in Flash or Bruce Wayne and his butler in Gotham or at least like Jor-El and Clark in Smallville. Have Superman guide Kara through her journey, we should watch her fail, we should watch her succeed, and we should watch her fight alongside superman not completely ignore him. Of course they might add that in the future of the TV show, but in my opinion I feel like i'm watching a lie because truthfully, Superman is much faster, stronger, and better than her (once he completely masters his abilities that is). They also mentioned that they are bringing in General Zod and I don't think it's right having Kara fight Zod without Superman, Zod is a major enemy to Superman. It's like having Robin fight the Joker without Batman or Cisco or 'Vibe' fight the Reverse Flash or Zoom without The Flash himself, just doesn't feel right. I know this comment might have mixed reviews but I repeat, this is just my opinion.
