Magus wasn't that deep... 'Oh, mommy was a meanie to sissy and summoned big porcupine and killed sissy. Until they made a sequel. Now I become Demi-Human ruler and pwnzer Lavos!'
Glenn's tale was more tragic and heroic, even if he was a whiner. Robo's story was actually okay, but only Asimov did the 'Robots take over the future' gig... Mother Brain was stupid.
Not to say I hate Chrono Trigger. I just hate the cast. I have respect for Frog and Magus. They're all just over emotional in their responses, and never stop to think. Ayla had no real importance to the plot, just game wise you needed someone strong who you didn't have to fork over an X amount of money to buy weapons for.
I kind of respected Crono and Marle's relationship, but not much more. I really hate them both, just respect their relationship.
Lucca was too goofy to be taken seriously, but CC did manage to do her a bit of justice.
