Good and evil fics. I hate good and evil fics. By this I mean fics were everything is black and white. Most Harry Potter fics are good examples of this, thou BtVS are truly horrible when it comes to this. I really can't put into words why this whole idea bothers me, it just does.
I don't really have a problem with good/evil fics; it's actually the ones where the lines aren't clearly drawn enough that piss me off. 'The Return' is an excellent example of this, what with damn near every faction either fighting each other or planning to stab someone else in the back, it's frustratingly difficult to figure out who are the good guys and who are just Murdock's (or Pluto's...) puppets. Agh.

Implied flame threat revoked.
Crystal Tokyo is a horrible idea, in any incarnation that resembles canon. Just no.
All my defense of Usagi as a good person (on the "Hotaru the Whipping Girl" thread) aside, I'm inclined to agree wholeheartedly. Utopias of any kind are doomed to crumble as soon as they face any kind of external challenge, no matter how good-hearted their rulers might be. I think Ranma makes this point the best in '1/2 a Neko Moon', so I'll provide an excerpt here to illustrate my point.
"Is it so wrong to want everyone to be happy?" Usagi asked, tears welling up in her eyes.
"When it's all they can be, yes," he responded flatly, "It becomes monotonous, things don't grow, they don't change. It's kinda like a stream, as long as water is flowing, things change, and life goes on, but when the water stops flowing, and the stream goes still, things become stagnant and life begins to fade away."
Haruka blinked, then shook her head, "Man, that was heavier than what I thought would come from you..."
Ranko blinked then shook his head in surprise, "Hey, you're right... Guess it's one of those changes, eh?"
"Could be," the short-haired girl agreed.
"But why does there have to be pain and suffering in order for life to go on?" Usagi asked tearfully.
"Easy, suffering, and struggle force us to grow, to get stronger and adapt," he responded, "Without something to drive us, to force us to grow, we get lazy and complacent. Weak I guess you could say."
"The Black Moon Family..." Setsuna whispered, "That's why they defeated Crystal Tokyo so easily..."
"Huh?" the black haired teen asked in confusion, "What are you talking about?"
"The Black Moon Family was a group that nearly destroyed Crystal Tokyo in the future," the crimson eyed woman responded, "They were a group of people that had refused Usagi's cleansing, and where banished to the tenth planet, Nemesis. Then, years later they returned, and nearly destroyed all of Crystal Tokyo, the Senshi from this time were forced to go into the future in order to stop them."
"... People were exiled from their world just because they wouldn't submit...?" Ranko asked in horror, "What kind of monsters would you people have become!?"
The girls all winced at the accusation, unable to meet his eyes, a small line of tears growing in their eyes. Mamoru's eyes glinted with anger as he challenged, "Who are you to call us monsters? What makes you so damn sure that your way is the right one!? We were trying to help people!"
"Often the best poison is made with the best of intentions," Ranko countered, "And as I recall, there was someone else that tried to make a perfect human race, getting rid of those who didn't fit in that 'perfection.' He was called Hitler."
The, seemingly, automatic assumption that the GW boys are together, this is so old. I would like to find one decent fic where this is not the case.
If you don't mind Sailor Moon crossovers (and a blatantly evil Mamoru), there's one... I'm trying to think of its' name and I'm having trouble, 'cause it's not in my archives, but it casts the G-boys as the princes of the various planets, and all of them are engaged to one of the Senshi; Hiro (Prince of Mars) is working up the courage to ask the Queen for Serenity's hand in marriage, and Duo (Prince of Saturn, who else would Deathscythe's pilot be?) gets Ami, I think...
If I find this story again I'll post a link.
