I had a ton of fun reading Infinite Jest, it took me two months of reading daily but after a while I couldn't wait to get home from work to read it (I didn't have a kid yet mind you). There are many things about it that are dissatisfying, frustrating even maddening. But there are so many points of brilliance it makes the whole thing worth it. The ambitiousness, audacity and shortcomings are part of it. I felt similarly about Pale King, DFW's posthumously published unfinished novel. Was it a great book? No. But there is about a 50 page section in the middle that makes the whole damn thing worth it.
