Unless the anime is REALLY rushed, leaves out alot, or adds on too much, then no. I like to ask myself the question, 'If I had never read the manga, then would I have still enjoyed the anime?' If the answer is yes, then there you have it.

Sometimes. I mean, if I really love the manga then I would hope for the anime adaption to follow, most the time not for the story but so aspects of the characters aren't messed up really. But sometimes an anime wont follow the manga and still does a great job so it depends.

It really Depends. As far as Anime is concerned, no. I don't read manga if It's to do with an anime. I do however, read Yaoi. I like my Yaois to follow the manga. But even in saying that, If they do something slightly different on the Anime, than is done on the manga that actually works well, or even better.. then I have no problem.

So aslong as the stry stays the same.. If they make changes that affect the story in a big way then I'm extremely dissapointed.

Never I don't care what happened in the manga and I don't care about that "canon" crap all I care about is if it's good

Except for TWGOK. The first two seasons were great! Then they skipped like half of the manga and just. that ruined it.

I try very very hard not to judge anything at all personally.
