What disappointed you about How to Learn and Memorize French Vocabulary?
The writer has a knack for never getting to a point, rambling over irrelevant anecdotes and speculation, then congratulating himself for his fine work. He can keep this up for a long time. The book could be replaced by a moment of silence.
What do you think the narrator could have done better?
In the introduction, he states that neither the writer or the narrator can pronounce French words, which proves correct.
