This article has been failed for GA. There are many problems with the article
The article is very POV
Very bold claims like "He was a Sanskrit scholar of supreme rank"
"He was able to explain the concepts, methods and practices of Koodiyattam and Chakyar Koothu in a clear and scientific way. He had an in depth study of Nātyaśāstra of Bharata Muni, as well as ways of acting which were popular in Kerala. His knowledge and mastery over both theory and practice of Koodiyattam were superb. " - blazing POV is presented as fact.
"He was the beloved student of one of the greatest Sanskrit scholars of all time "
there are many examples of this trhoughout the text
Too many peacock phrases such as "coveted" and "prestigiuous" this is all in the lead
The early life section is largely unsourced.
There is a large proliferation of grammar errors throughout the article.
"Master of Rasa-Abhinaya" section has many grandiose claims that have no source:widely acclaimed, iummortalised, etc, etc stating that he is extraordinary as a matter of fact.
The section also almost entirely consists of single sentence paragraphs which pay tribute to him and use honorifics against the WP:MOS
These themes recur over and over throughout the text.
