The One and Only Problem I have with Slayers...

... is its repetitiveness on one point: The effect of the Giga Slave.

In Slayers, Sylphiel tells Lina that the Giga Slave could destroy the world, therefore it must never be used.

In Slayers Next, Lina gives this as a reason she wants to learn the Ragna Blade.

Also in Slayers Next, after having already stated the above, she sees a Clair Bible entry which shows her how the battle with Shabranigdo could've gone completely wrong. Lina acts like this is a surprise to her, even though Syl told her as much almost a season ago.

I dunno, I guess maybe the writers felt they had to drive the point home for some reason. But it still kind of irks me.
