Acceptable Religious Targets: The Fellowship of the Sun is full of vampire-hating people who feel it's their right to tell people how to live their lives. They also preach vampires and other supernaturals are an abomination in God's sight. They're not above blowing things up or killing people to make this point.
Alternative Character Interpretation: Sookie - An unfortunate woman who's been "Crazy ol' Sookie" for so long she doesn't know how to be anything else or a professional victim who doesn't want to be anything else? Is Sookie a hard-working, innocent woman, brought into a world she doesn't belong in and ends up having her heart broken by many men? Or is she just a nosy shrew who keeps putting herself in these situations, and cruelly toys with her men and breaks it off with them whenever she gets pissed?
Anti-Climax Boss: Sookie accidentally sets up Claude's downfall by mentioning he's gay. This leads to his minions, Johan Glassport and Steve Newlin to turn on him, allowing Sookie to escape. A nameless minor character shoots Claude about two pages later.
Anvilicious: We get it, Charlaine Harris, it's a metaphor for gay people and how they are treated. The books may also be poking fun at using mystical creatures as metaphors (elves, zombies etc.). Hell, Eric even calls Sookie out on using a bad metaphor (comparing vampires to lions) in the fourth book.
Base-Breaking Character: Sookie's become this in later books. This is in large part due to shipping as her relationships move increasingly away from Eric (and to a lesser extent) Bill.
Creator Backlash: Charlaine Harris wanted to end the series with Dead and Gone but was effectively forced by her publishers to continue the series due to the ongoing popularity of True Blood. This, combined with the fact many fans confused the series with her books, resulted in her getting increasingly fed up with it. Some people believe this is why the final books were so harsh and against the characters.
Ending Fatigue: The tail end of the series is less about the mysteries and more about giving closure to characters and storylines. Due to having so many characters and having to shoot down Sookie's chances with love interests, this takes several lengthy books.
Ensemble Darkhorse: Pam and Bubba. Hunter's also become one, having been the focus of speculation and fanfics.
Amelia. Many people are miffed at the thought that she might not be adapted into the TV series.
Ho Yay: Jason and Hoyt, Jason and Mel. Deliberately on Mel's side, because he's gay.
And, In Dead In The Family, Claude and Dermot, two of Sookie's fairy relatives. Claude's actually gay and Dermot is...questionable. They sleep in the same bed at the end of Dead In The Family, albeit with Sookie. The book ends on this mildly incestuous OT3 image.
Not forgetting Mustapha and Warren. At the end of Deadlocked, Sookie is literally left "confused" by their open display of affection.
Nightmare Fuel: There are several instances of torture and/or particularly gruesome deaths.
Strawman Has a Point: The anti-vampire cult that wants to destroy vampires because they are inevitably evil predators guilty of at least one casual murder, initially presented as the equivalent of various real-world anti-gay movements... is entirely correct in their assessment and makes a good argument in favor of their course of action. This is lampshaded occasionally by Sookie, who recognizes that her motives in keeping the truth from the normals are selfish and probably amount to abetting murder herself, and becomes a plot point when one particularly ancient vampire initially agrees with their plan to the point that he's willing to help them out even though it means dying himself.
Tear Jerker: Adele's funeral. It shows how beloved she was in Bon Temps.
They Wasted a Perfectly Good Plot: Nothing much ever comes of Sookie's occasional ability to read vampire minds when it could have been an interesting source of conflict.
