These all come from her. Her wording. Really surprised she didn't say, "Because I haven't seen any of the other seasons."
  1. "Cause I don't give a shit."
  2. "Cause he pushed the little boy off the castle."
    Mom is referring to the pilot, with Bran, you all know.
  3. "Too bloody."
  4. "Too incestuous."
    Mom is basing this off the 1st and 2nd episode.
  5. "It's depressing in how it portrays man's incessant need for power."
