Well, as an answer to that, people here feel obligated to do so as a time-honored (or dishonored, give or take your optimism) tradition of taking punches at a franchise only a small demographic of the entire world would like <---(This is a backhanded insult, FYI).
I guess the main reason why the majority of us here, specifically, don't like WC is because the personification does almost nothing to change how cats really behave, and minus the sub-par supernatural aspects of the Clans' roles, there's nothing in there that we already don't know about nature : its denizens kill and destroy each other for survival, guaranteeing the next generation as the progeny of the first. What's worse is that a bunch of old ladies (I have the right to say that, and relative to my age, it's true) have tried to release a very fluffy, no-thorns version of what natural life really is to a bunch of kids that don't know these correlations between fiction and real life (or are just beginning to see, though the skill to relate text to real-life takes years to perfect), mixed in with some strange take on Native American (as I can see it, spirit animals and reincarnation are pretty close to the general lore) culture...just doesn't get my reading lights blinking.
Oh, and don't get me started on the introduction of Shadowclan / whatever its name is. That just brings bias to a world where no one faction should be truly good. That's just raising kids to say "this guy is EVIL because he's unorthodox and doesn't stand even CLOSE to my beliefs!".
Yeah, no.
But, because this is the Internet...

^I knew I posted this earlier somewhere. Anyhow, I took my precious free time to bleed through the synospis of the story thus far, and my opinion of it...has only turned fo the worse. Clearly, Bloodclan had the right ideas for the Forest.
