Okay, that's a cute twist, making us think it's Doomsday and then doing Bizarro. Still, I can't say I care for how ineffectual Superman has been this season. I don't like seeing him fail over and over. Not for the dumb macho reasons of people who get offended that Supergirl can outfight him, but the idea of Superman as a protector and rescuer is important to me, so I don't like seeing him unable to help people.
Things with Sarah aren't going as I expected. I thought they were going to split her up with Jordan and have her start dating Natalie.
It's interesting that the damage to the Steel suit was largely in the chest area. I wonder if maybe John and Natalie will rebuild it with the Superman crest, maybe to counter Anderson's bunch appropriating it.
Sam's line about Lucy not being as strong as Lois, and the implication that she's still under the cult leader's sway, suggests that, even though it's the same actress, this version of Lucy is going to be a radically different character from the Earth-38 Lucy of
Supergirl's first season.
Has Bizzaro ever been done in live action before?
As mentioned above, the 1988
Superboy series did an excellent, very faithful version of Bizarro played by Barry Meyers, featured in three 2-parters and making a smaller appearance in a late episode. The evil Superman in
Superman III was loosely inspired by Bizarro, and
Smallville and
Supergirl did their own one-shot versions.

Lucy Lane was involved in his first comic book appearance
You're confusing two different stories.
The 1958 Superboy issue that introduced Bizarro had him sacrifice himself to restore the sight of a blind girl named Melissa. Lucy Lane debuted
six months later in
Superman's Pal, Jimmy Olsen, where she was Jimmy's love interest. The 1986 John Byrne
Man of Steel reboot told a new version of the Bizarro story with Lucy Lane as the blind girl; that's probably the story you're thinking of.
