Yeah, it's that bad. It pretty much killed the whole concept of big Bat cross overs. Bruce is a dick and acts out of character even for that time where he was supposed to be a bitter jerk, Stephanie is made to come off incompetent then brutally "murdered" for the sake of shock value, they make Leslie Thompkins act out of character by "letting" Stephanie "die" to teach Bruce a lesson, and just a whole bunch of other stupid crap happens.
So yeah, it sucks, a lot.
Yet, compared to a certain retcon which lets Leslie off the hook . . .
Show me a bitter nazi and I'll show you a sour kraut.
