You know, I'd read in some posh literary review that Jake and Brett were two of Hemingway's most lovable characters, but I really can't see how that could be. I get he was painting an era, but I had the same difficulties I had with Fitzgerald's "Great Gatsby": I was bored by the characters misery (first world high class problems, people, that's what you have!); and I was enraged by the chaos and destruction they sowed all around themselves with their callow carelessness. Stupid egotistical brats.
And that's the other thing: they ARE reacting like brats. "Our parent's culture and ideology crumbled down and betrayed us! Let's rage and get drunk, and screw everyone around!" Except, you know, they are in their middle thirties. I don't say you have to have your shit together by that time or any other, God knows you never really do, and life has a marvelous way of sucker punch you when you think you have it balanced, but the over the top woe-is-me shit you are supposed to learn to manage after the hormones of puberty stabilize.
Every generation has challenges, and I reckon those that were born around the turn of the 20th century had a suck-fest of a raw deal, but what I saw inside this book was not just depression and insecurity over lost direction and of self, but a total lack of care for other people. I saw the phrase "moral bankruptcy" around, and I think that's and exact description, but it was treated as an excuse for how these particular characters act, because apparently it was a pervasive thing all around. News-flash: if everyone is a terrible person, and you act like everyone, you are still a terrible person.
So no, I have no love for these characters. Now, do I have any use for this book? *sigh* Thorny issue. If it was an accurate representation of the generation, I have to loose any surprise at seeing them fall right back into war; they all felt suicidal to me, and self-centered enough to blow up the world along with themselves.
So here's what I think: maybe it's useful, but I did not like it.
