Any critical reading of Pynchon's works proves worthwhile, and the sheer variety of approaches speaks to Pynchon's density of prose and themes. Tanner's gloss is interesting but not as philosophically creative or exhaustive as others available. In addition, it only includes Pynchon's works up to Gravity's Rainbow as that was all that was published at the time of writing. And yet I discover, as with almost all critiques of Pynchon, that I immediately want to set down whatever fiction I happen to be reading, and pick up the closest Pynchon novel to begin and discover again.
