I agree on that one!

Often time I have been tempted to complain about a bend not looking 'right' only to try it myself in the mirror to see how it should look and find out that the pose itself is beyond what the normal human body can attain.  Also sometimes the bend we think we are trying to do with one joint should really be accomplished with 2 or three joints to look natural. (for instance looking way up is going to invovle the neck head and chest bends and maybe even the abdomen to a small degree)

It would also help things along if we lock the rotation limits so that the figure always bends realistically, providing a pose or something to unlock the figure's limits for those who may need to push a pose beyond realism. With a locked figure, you're less likely to run into situations where the bending doesn't look so great.
