Gary Sinise's performance of Of Mice and Men is one of the best audiobooks I've had the pleasure of listening to. Even if you have read this book, I highly recommend listening to it. It's three hours long, and only an hour and a half if you crank up the speed of the narration. That's shorter than most movies. But make sure you grab Gary Sinise's narration. There are several versions on Audible, so make sure you sang the right one. The Sinise/Malkovich version of the film adaptation is my pick, as well, you know, if you prefer the cinematic experience.
Of Mice and Men was the first unhappy ending I ever experienced in literature. I've been a fan of stories about flawed characters and bleak finales ever since. I know how dark this sounds, but happy endings bore me. They're always so... expected, I guess is the proper word. I go into every story--whether it's movies, video games, or books--assuming that everyone will live happily ever after, because it's marketable and that's what the vast majority of people want. Not I. The darker the better. I dig bleak, man, what more can I say.
In summation: You don't get much more tragic than Of Mice and Men. If you're a fan of flawed characters who are forced into tough, heart-breaking decisions, look no further.
Final Judgment: I will name him George, and I will hug him and pet him and squeeze him.
