As pointed out in commentary written by dramatist Yao Yi-wei, collective improvisation is not a formula which just anyone can apply. In the hands of the wrong person, it results in a proverbial case of "turning a botched attempt at painting a tiger into a dog-like something-or-other."
劇作家姚一葦也曾為文指出，集體即興的創作方式不是人人可以採用的，否則會有「畫虎不成反類犬」的反效果。
