Glenn Quagmire (seasons 8-17)

Glenn Quagmire is a recurring character in the FOX adult animated comedy series Family Guy. He is the neighbor of the Griffins, who is known for crazing over sex 24/7.

Why He Sucks In The Newer Seasons

 * 1) He went from a kind of pervy ladies man, to a repulsive sexual predator who knowingly and gleefully shares his numerous STD's with the women he sleeps with (lying about wearing protection if he needs to), making him extremely unsympathetic to the audience despite how many times the show tries to give him sympathetic episodes (his sister being in an abusive relationship, him being tricked into marrying a prostitute, him being trapped in an abusive relationship with a "female Quagmire", etc.)
 * 2) He can be seen hitting on Lois Griffin constantly.
 * 3) Ironically, he says he likes women for their bodies rather than their personality.
 * 4) Glenn Quagmire isn't just a pervert, but a child molester.
 * 5) *In fact, he is summed up a "pervert" in one word.
 * 6) He's overly talkative, especially when it comes to sex.
 * 7) He abused Brian Griffin two times throughout the series, the first scene was when he severely beat up Brian Griffin, which is animal abuse, the second scene was when he broke Brian’s teeth with a lamp. (Although, the second time was justified since Brian scammed him into buying a run-down lot, despite that Quagmire helped Brian get his teeth repaired in the beginning.)
 * 8) He shot Peter Griffin in the head in the episode “Brian’s a Bad Father”. Joe wasn’t much help either in the episode as he shot Peter in the right bicep. Peter did shoot Quagmire earlier in the episode, but QUAGMIRE NEARLY KILLED PETER! (How could Peter possibly not hold a grudge against them for shooting him?!)

Redeeming Qualities

 * 1) At least he is not as bad as Brian. Well, it depends on your point of view.
 * 2) Despite hitting on Lois, Quagmire is very loyal to his best friend Peter as he would never try to hurt his feelings by stealing Lois from him.
 * 3) He is likable in many episodes.
 * 4) Spawned a lot of memes.
 * 5) Although he developed a hatred against Brian, this was not the case during Seasons 1-6. But then the fans of hated on Brian, which may be the reason the writers decided to make Quagmire hate Brian.
