The endnotes are fundamental to the experience. There are some key plot points divulged or hinted at there first (and sometimes there exclusively, IIRC). Pemulis' funniest moments are back there. I still find my mind drifting to the description of Cage III: Free Show from J.O.I.'s filmography from time to time.

If nothing else, I once read a comment somewhere online that noted that the constant back-and-forth from text to endnotes and back is physically analogous to a back-and-forth in a tennis match. If thematic consistency in the third dimension was actually something DFW was going for, it's a shame you're only seeing half of the court.
