I must have watched this movie a hundred times, and I never grow tired of it. It's just like you said - following all the plot twists is kinda pointless in the end. And it's not always easy to get it at a first glance; I recognized the greatness of TGL after 2 or 3 times I watched it. It's now steadily in my top 5 of all times.
Yeah, I guess I share most of the Dude's values. I am extemely lazy and definitely a pacifist by birth anyway, so it wouldn't be very hard for me to follow literally that kind of philosophy :D
