These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nekron crosses it twice: first by causing the dead to rise and attack their loved ones, and then by killing eight of the ten resurrected superheroes (including Superman and Wonder Woman) and turning them into Black Lanterns, all the while being in an And I Must Scream state forced to watch themselves attack their friends and loved ones while slowly dying.
Padding: The Parallax vs. Spectre fight: while providing an emotional callback to Rebirth, it comes off as this when both were promptly dismissed once the fight was over. Arguably, the deputy Lanterns also don't end up contributing that much to the storyline beyond fighting Nekron's Mooks (and, in the case of the Agents Orange, each other); it can feel like they (with the exception of Ganthet, who joins the Green Lanterns permanently) were Rule Of Cool-inspired Padding tacked on in the attempt to expand the original Lantern Family Crossover into a Crisis Crossover.
Unfortunate Implications: Several fans, especially female fans, were known to have dropped this series with the third issue, thanks to that issue's death which was played disturbingly like a rape. This was not helped at all by a later tie-in issue in which a Black Lantern who had actually, canonically been a rapist in life was discovered eating the body of the issue 3 victim.
Villain Decay: While this could be considered literally true for all the zombied Black Lanterns, other villains like Larfleeze are getting this treatment. In his first appearance he ruled over an entire solar system, possessed the power of an entire corps, dictated terms to the Guardians of the Universe and commanded his own army of wrathful shades. Now he appears much diminished after his first confrontation with the Black Lanterns and his artwork has changed as a result. He is also drawn much smaller and less menacing and seems now to be more of a comic relief than anything.
Justified as well. Saint Walker offers to curb Larfleeze's hunger with his blue ring for as long as he helps in the fight. Not the most sane choice when the man's power directly stems from how hungry he is, but then again, he might have pretty much hampered if not outright ruined the entire shebang solely trying to steal the others' rings.
Also, Larfleeze didn't rule much more than his swamp. The people native to the Vega System, including one of the G Ls Larfleeze kills, don't seem to know much about him. Larfleeze COULD have ruled, but he was too busy eating.
The Woobie: Osiris had it bad enough in 52. Now, not only is he the only Black Lantern to retain his humanity, but his sister and brother are dead. And everyone is afraid of him. And Sobek is murdering people just to get to him. The poor kid just can't catch a break. Although in the end, he is given a true second chance at life thanks to the White Rings. Which gets subverted in Titans when he participates in the murder of Ryan Choi and gradually becomes the killer everyone accused him of being..
Maggie Kyle is now one too, given everything which had already happened to her in the Catwoman monthly book (which was being tortured with her husband by Black Mask, having her husband die, being forced to eat her husband's eyes, and being committed). After escaping from Black Lantern!Black Mask, she has now snapped completely and gone insane.
