The layout of this article leaves a lot to be desired. The "composition and significance" section does not explain why the Bhagavad Gita is the most important part of the Mahabharata, who thinks so, or if anyone disagrees. The second section contains two lists. I am of the opinion that for a work of prose any lists of chapters should be at the bottom of the page so that readers can enjoy a narrative summary before they break up their understanding into 18 pieces. The next section is "themes" but we are not really sure why these are the central themes. These could be better integrated into the "background" paragraph.
Contrary to the prior reviewer I find that the references are sterling. The facts are there, they just need better organizing.
It is broad in its coverage.
a (major aspects): b (focused):
Although I am personally aware that this is a decent summary, it is unclear from the way the article is laid out if everything in the poem was really covered.
