I am a latecomer to the work of Nicholas Roeg. As a scifi fan, "The Man Who Fell To Earth" was a library discovery a year or so ago and was very much enjoyed. In my quest to "understand" 70's film (an era I was only alive for 8 months of), I saw "Performance" a few months ago. And finally, I saw what I consider his best of the three: "Walkabout".

It's hard for me to write about Philip K. Dick. For one thing, my attraction to his writing more or less defies my explanation. It's to the point where it's his voice I love more than anything else; yes, he's got an amazing imagination, and plots, and all that, but what really gets me is his characters' thought patterns. They're simultaneously the last thing you'd expect people to do/say and amazingly right and natural. I don't know how to reconcile this contradiction, but it's where my love for Phil lies. Even his "not as good" books are fondly remembered for their characters, or scenes, or ideas.
