Platonov is "must read" if you interested in Russian literature but he's not that great.

Vladimir Sorokin wrote that he was fascinated by Platonov but soon discovered that it's too easy to imitate Platonov style.

Platonov chapter in "Blue Lard" is even more Platonov than Platonov himself.

Disregard what I said I encourage to read "Chevengur" - it's super.
