Daenerys Targaryen (season 8)

Daenerys Targaryen is one of the main characters of the A Song of Ice and Fire novels and the HBO adaptation Game of Thrones. Initially one of the main protagonists, years of trauma, loss, fear, and jealousy cause her to be Flanderized into madness and vengeance, becoming the TV show's final antagonist.

Why She Sucks Now

 * 1) As mentioned above, she is totally out of character in the second half of season 8.
 * 2) *Generally, people see Daenerys as a kind-hearted, polite and well-spoken figure. In fact, she had turned into a vengeful and callous tyrant who only destroys to fuel her own madness.
 * 3) *After Cersei and her army surrender to Daenerys' army, she responds by obliterating King's Landing, without regarding the lives of thousands of people.
 * 4) *One could argue that she turned villainous because of all the difficult situations she was currently facing, but other characters, including herself in previous seasons had been though worse and showed no signs of going insane and becoming a villain.
 * 5) She was executed instead of Varys by Jon Snow, when the latter actually plotted to overthrow and betray Daenerys due to her worsening state of mind.
 * 6) In "The Bells," her decision to burn everything, including the common folk, contradicts all her previous efforts throughout the series to save and free the innocents with no good justification or development.
 * 7) Her Flanderization into madness reduces her character to her lineage, turning her into a tragic hero destined to be evil despite her previous choices and her effort to be a fair and good ruler, making all her previous struggle and development pointless.
 * 8) Even her actress, Emilia Clarke had stated that she was so shocked about her character's Flanderization that after reading the script she walked out her house aimless for five hours and called her mother for advice.
 * 9) Her character development in the second half of Season 8 felt rushed, as writers David Beinoff and D.B. Weiss rushed the final episodes just to work on their upcoming Star Wars project, where they eventually left.

Redeeming Qualities

 * 1) She used to be a good character in  of the TV show.
