MoMA: Abstract Expressionist New York (3) Preference?

There were many works from different artists. I found some good, some not so good, some total nonsense---but they are all picked as works worth showing in the same exhibition. I found it was really interesting. Here are some pics. I graded according purely how much I liked them--you can give grades of your own. I would love to hear your opinion!
Here we go.

<B> out of A( I love!) to C (it's a crap!)

<A>

<A> ! For some reason, it looks beautiful...

 <C> What is this supposed to be?

<B> I do not mind putting this on my yard (if I have one)--- for some reason.

<A and C> I like the first pic, but not the second one. Do not ask me why.

<A and C> Again, same painter but I like the first one, I hate second one.

 <A> OK, this black picture supposed to have 3 "shades" of black. Which I did not see. But I like the guts and elegance! The MoMA panel said that somebody resigned from membership when the museum purchased this picture. What is a shame! What is the point of having a Museum of Modern Arts?

MoMA: Abstract Expressionist New York (2) Rothko

I had a chance to go back to the exhibition to finish going through it before it ended. Many pictures and some interesting observations....let's take a look.

1 Rothko

Surprisingly (or not,) it took him very long time to form his "style." The process was clearly shown at the room with many pictures of Rothko from different periods.

Those 3 pictures represent well of the change he went through over time. Here is a quote by Rothko from MoMA's panel which explains the idea perfectly.

"The progressive of a painter's work, as it travels in time from point to point, will be toward clarity: toward the elimination of all obstacles between the painter and the idea, and between the idea and the observer".

 I found this quote quite deep. It feels so true--it may apply to any kind of art. To convey what you see and what you felt---exactly how it felt---to the canvas (music or writing, whatever the form you take) to convey to the observer as pure as possible! If you are (or tried to be) an artist, you know that it is indeed what you aim at, and how difficult it is. In a meanwhile, arts is the most powerful tool to "eliminate obstacles" which exsits between people and people for understanding each ideas and feeling--- "between painter and the idea, and between the idea and the observer."

Rothko took further pass to stop using bright colors (2nd and 3rd picture). Here is another quote from MoMA explaining the picture No. 3.

"often, towards nightfall, there is a feeling in the air of mystery, threat, frustration ---all of these at once. I would like my painting to have the clarity of such moments."

What do you think, how good he achieved his goal?
