Why I personally dislike the art movement of Mannerism (FW)

What is Mannerism?
Mannerism was a 60 year art historical period that started around the end of the Italian High Renaissance (1520) and continued until the start of the Baroque Period (1580). It is characterized by distorted body proportions (freakishly long necks and long legs), irrational settings, precarious poses and tension. 

Now, why do I hate it so much?
  That is a much more difficult question. Whether or not art is good is completely subjective. The things that bothered me most about Mannerism might appeal to another person's tastes. I can't say that Mannerism is bad or good because that is a opinion. However, I can state why I personally found it so completely disturbing.

Why I found Mannerism disturbing:
1.) Body Proportions
This painting by Parmigiano is correctly named "Madonna with the Long Neck" (1534)
Check out how huge that baby is. No baby should be THAT BIG. No neck should be THAT long. We can assume that Parmigiano mean the body proportions to be unrealistic, but why? I can't really understand his reasoning except that there are a lot of normal-necked "Madonna with child" paintings and mannerist artists liked to be original.
2.) I'm claustrophobic...
and the colors...
   This painting is "Entombment" by Pontormo (1528). The body proportions are not excessively stretched in this artwork which is a plus, however I am bothered by the color scheme and the act that Pontormo crammed ten people into a painting that should have held three. All the people are so distracting that I feel I can't focus on what the painting means. It takes me a few seconds to find Jesus each time I look at this painting because everything else is SO DISTRACTING. Also Pontormo chooses to uses pastels in his interpretation of the entombment of Christ which I feel is a bit too cheery for the situation.

 3.) Uncomfortable subject matter
  (1545)  "Venus, Cupid, Folly and Time" by Bronzino
Since the Renaissance was such a period of artistic growth and exploration, those in the Mannerist movement realized that they had little to explore other than new subject matter. This is how we arrive at a disturbing portrayal of a grown Cupid in an affair with his mother, Venus. I really like they symbolism of other parts of the portrait such as Folly carrying flowers and jealousy looking on with anguish but the whole mother-son relationship is too disturbing to look past. 
4.)Art for the Artist's sake
 "The Rape of the Sabine Woman" -Giambologna
I love this sculpture. The emotion is shown so clearly in the body position and it really shows off incredible artistic technique. This sculpture is so good that when I first saw it I felt that it might have that ability to redeem the Mannerist period. Then I researched it... Giambologna created this piece for no other reason that to show off his own artistic ability. I felt duped. I had felt like this sculpture makes so many statements, and I was truly dissapointed when I realized it wasn't meant to make any. The structure of this is still really impressive though. I'll admit that.

Reasons why Mannerism is okay
Mannerism really worked to push everyone outside of their comfort zones. Artists took on risky material and tried out new methods of creating a scene which were unheard of in the Renaissance. It's awesome that society allowed them this much artistic freedom and expression. I just didn't really like the products. However, I can appreciate the fact that Mannerism elicited such strong emotions from me. I'm sure the artists realized at the time that what they were creating would outrage a lot of people. I respect that they went on to create the art anyways.
