Gotham Central/YMMV

• It Was His Sled: Renee Montoya is gay, Two-Face stalked her and she begins to descend into violence and alcoholism as the series comes to a close. Her history is one of the basic premises of 52, a very successful and high-profile series that picked-up after Gotham Central ended, and Gotham Central itself received a lot of press and critical response (Including three awards) for this arc. To many comics readers the series is known as "the one where they outed that chick from the cartoon."
• Moral Event Horizon: For a while Corrigan does not seem like too bad of a Dirty Cop, no worse than the usual evidence-tampering scum of Gotham, but when he starts torturing other cops and kills Crispus Allen, he stops being small-time petty evil and becomes somebody asking for a bullet.
• Tear Jerker: If you can get through this series without reaching for a tissue at least once, you are simply inhuman. Every character experiences loss, defeat and horror that no person should ever have to go through, and then they soldier on and keep going, slogging through more heartache until the end, because everybody knows "It's Gotham."
