I like Michael's/Lex's style in speech, manners, class & dress. But especially his smooth, clever & highly intelligent way of speaking. It's how I prefer my style.
I think him & his father have the best dialogue on the show. You can actually learn things from them just by watching & listening to them. Whether it be a new word, unknown facts in the history of powerful men, how business is an aggressive man's game or simply how to dress well.
