That the writing is subjective and hence too colorful and wordy is evidenced by the remark, "what I find most interesting about them".

Edit: It is however not as long as I derided in another comment. At least there is a link to a relevant paper in the beginning, although further reading didn't appeal to reading that paper. The text is almost half as long as the paper, that's too long for a summary. I'll refrain from more critique as I'm far from an expert on literature.

Your comment is ironically very wordy as well, but I concur.

Edit2: I am not seeing sources for the images.
