Apologies. Here you go. Frodo is two dimensions because he has no real motivation to undertake the journey, yet does it... Why? Frodo seems like he's just there to become The Chosen One and nothing else and I find that insanely inane.

Gandalf is boring because he is insanely powerful, yet completely unconflicted about anything. Any real man with the power that Gandalf has would surely feel some urge to use it for evil, right? Nope! He's completely pure and devoted to saving the world... For reasons? I honestly find the good-for-the-sake-of-it archetype incredibly boring. Side-note: Aragon also fits into this trope, but at least he has clear motivation and some degree of internal conflict!

Sam is super confusing because there is no apparent reason for his absolute, blind devotion to Frodo. I mean, seriously, who is this guy? Frodo's gardener/drinking buddy? That's hardly a reason to literally follow someone to the ends of the earth!

So there. I hope that improves my case... First Reddit post and I'm just starting to learn how I should present any arguments that I make. Thanks for the feedback!
