Infinite Jest is an enormous yet rewarding read, and is one of my top five favorite novels.
It is a fact that Infinite Jest is a long book with almost a hundred pages of endnotes, one of which lists the complete (and fictional) filmography of a prolific (and fictional) filmmaker and runs for more than eight pages and itself has six footnotes, and all of which you have to read because they are important. So sure, it’s a lengthy book that’s heavy to carry and impossible to read in bed, but Christ, how many hours of American Idol have you sat through on your uncomfortable POS couch? The entire run of The West Wing was 111 hours and 56 minutes; ER was twice as long, and in the later seasons, twice as painful. I guarantee you that getting through Infinite Jest with a good understanding of what happened will take you a lot less time and energy than you expended getting your Mage to level 60 in World of Warcraft.
So, go out and get a copy right now, and dig in. You won’t be sorry.
