That would explain it’s resemblance to an evil lair.

Yeah, make Twilight earning herself a castle WITH BLOODY, GODDAMN THRONES FOR HER FRIENDS a bad thing.

The castle symbolizes Twilight’s bonds with her friends. You paint the castle (and the five key episodes and Rainbow Power) as a bad thing, and you’re painting friendship as a bad thing. You are also going up a step by praising the Twilight/Tirek fight, even though it outright disregarded Twilight’s friends.

Which leads to one conclusion, you WANT Twilight’s friends to be gruesomely tortured, raped, victimized, and murdered by Tirek, just to make Twilight more overpowered. After all, it worked with DBZ; it victimized and brutally murdered characters like Yamcha, Vegeta, Krillin, and Piccolo, just to make Goku more and more of an overpowered savior. Never mind teamwork, which was actually promoted in other shows released at the same time as DBZ, such as Teenage Mutant Ninja Turtles, Mighty Morphin Power Rangers, and Sailor Moon. Nothing but torture and rape of characters we once thought were powerful when they weren’t, from Yamcha and Krillin, to Twilight’s five friends!
