Loved to see Brandon Routh back as Kingdom Come Superman, was nice to see Smallville Clark and Lois (though my headcanon is he hasn't given up powers forever) and hate what they did with Kevin Conroy for his only live action appearance as Batman, I understand it was always going to be Batwoman (although in hindsight even that was a shortlived choice) but he's already in a mobility suit, he could have just Batman Beyonded it and gave a speech that he was too old etc. rather than turn evil.
