Fandom-Specific Plot: Not surprisingly, a regular plot point is where Sakura Hagiwara and/or other characters enter a wrestling match against various crossover characters.
Too Bleak, Stopped Caring: Sakura is a novice in the wrestling world so she repeatedly gets her ass handed to her, and many of her fans turn on her, shouting how much she sucks and that she let them down. This turned off many viewers early on, who thought the show would be nothing but Sakura being humiliated and hated on over and over. By the end of episode 4, things turn around and the series gets much more even-handed- she's still challenged in the ring but has more expertise under her belt, so she doesn't seem so outclassed. Of course, before that point, a lot of viewers had dropped the series.
