Why do readers hate Mary Sue characters?

Let me number this to make it easier for me and you :D

1. They're boring

2. They're one dimensional, card-board cutouts

3. Quite often we as the readers/viewers get that they're "perfect" shoved down our throats, when more often than not they're not perfect (for instance, they can act bratty, and other characters will not notice they're acting like brats, or will think it's cute or something)

4. They're too predictable

5.They're unrealistic in almost every way

6. They never change, and never have any form of development

7. They're usually "average-looking, nothin special, plain-jane girls" yet somehow every guy in the story usually falls in love with them

8. Instead of making things happen in their lives, things just magically happen to them

I don't get jealous of Mary Sues, just extremely annoyed, and they're almost always the main characters of things. This isn't just in Twilight, either. Sadly Mary Sues have invaded media all over the world (especially in shoujo anime) :( It's a sad thing.

Jealousy may be a reason for some, but it isn't the main reason. If you're looking for well-written, three-dimensional characters, you won't get that with mary-sues because they are written to be perfect. If they are given flaws, then these flaws are 'romanticized' or made to look cute, thus making the character even more 'appealing'(in the author's view, anyway). It's annoying to read about 'perfect' characters who get everything they wish for. It makes them hard to relate to, brings the impression that they are the 'author's pet', and they are just not well-developed characters.

Bella from Twilight has been mentioned a lot already, but she IS one of the biggest mary sues i have come across. Despite getting attention from the guys, and particularly from the most handsome of them all, she still thinks she is all plain(making her sound humble; but it really is just a quality of a mary sue). Plus her clumsiness is made out as a flaw, but it isn't really a character flaw; it just helps add to her 'cuteness' for the guys.

Readers tend to dislike Mary Sue characters because they are yes, too perfect. They're not jealous. Well, I guess some might be, but that's not the general reason for disliking them. They grow tiresome to read about -- in the end, it's almost a given that they'll get what they want. They're good looking, smart, and something convenient always happens to their advantage. People want to read about characters with more flaws, characters they can relate to. They want to know what happens to the realistic characters, not the ones that are perfect. ;]

Bella Swan from the Twilight series comes immediately to mind with that. She's supposed to be average, but if you think about it: she's apparently attractive enough to have a line of boys falling at her feet on her first day at school; from almost one hundred years of living the boy who is arguably the most attractive in the school falls for her too; she lacks any real character flaws apart from being clumsy and, y'know, dating a dangerous supernatural creature; and without giving too much away, towards the end of the final book what happens is *very* typical Mary Sue. I don't want to elaborate in case I spoil it for anyone who enjoys the series and has not gotten that far yet. And also, a lot of the Twilight fans I talk to agree that Bella is a boring character to read about. Mary Sue? I get the feeling so.

Sadie, the protagonist of my current novel, (I didn't name her after myself, I used her name for this account) was a little too perfect the way I first envisioned her. That was a response to my last protagonist, who irritated my readers a little bit, and who I wanted to kill by the end of it. However, I didn't worry, because Elsie, the annoying protagonist just mentioned, had (shockingly enough) started out perfect as well. Sure enough, flaws emerged organically as the story unfolded. Sadie is still a sweet, subdued little girl, in line with the times she is growing up in (the 1890s). But, I noticed a pattern of her having thoughts of jealousy. The story is in first person, and from the way she narrates it, I can see that she is bitingly sarcastic inside her private thoughts. And, although she strives to match up to the ideal little lady of her times, there is a little corner of her that, I think, would be rebellious if she wasn't so eager to please. So just start writing, don't worry about your character being perfect. Don't insert flaws just because, let them come naturally. They will. Best wishes!

Mary Sue characters leave little room for character development because they're supposed to be perfect which leads to a boring story. Bella from Twilight is one. I hate her because she is too dependent on Edward to the point of jumping off a cliff to hear his voice. She begs him for sex. This is odd because Bella is supposed to be Meyer's self insert of herself so she tries to make all of Bella's flaws look cute but I guess she overlooked the fact that she made Bella a complete anti-feminist and a horndog and possibly a total snob and whiner yet somehow, she gets every guy at school ogling her.

My problem is not with the term, my problem is with the retard who misuse the ******* term.

A Mary Sue is a character in which the author identifies so strongly with, that the story is warped by it.Mary Sue is NOT gender specific.

Because they make boring stories.

Heres a guy Mary Sue char- Edward from Twilight, most boring character ever.

They are way too perfect and generally annoying. I hate my own Mary Sue's the most. The worst I ever made was this girl who kept changing her name. I took this quiz( http://www.springhole.net/quizzes/marysue.htm ) and she scored a 93, worth "Kill it dead."

you thought you hated mary sue,but mary sue hates you! (and doesn t want you as the authors of her story,thats all)

so they get offended that they can never please her... they made her real in a sense.. and are jealous.
