Ummm Halloween and The Thing are probably the MOST typically aesthetic of his films. In fact, those two films DEFINED his aesthetic.

I disagree. They are made in his aesthetic. Look at the writing. In most Carpenter films(including Halloween and The Thing) the characters are fully formed and do not seek out character development, nor is there really an emphasis on backstory. Another element of his aesthetic is that the characters represent the film's ideas as a whole. In Halloween Michael and Lori represent repression, both sexually and socially, they are sort of a yin and yang.
Almost all his movies fit this style at their core. Along with a minimalist approach, sort of similar to the simplistic approaches used by Jean Luc Godard.
