I have lost my sense of humor to some extent. A decade ago, I liked this book when I read it. But now, arbitrary flights of fancy are hard for me to take, even when they are meant to be humorous. Does this work as a skewed detective story that involves ghosts, aliens, and time machines? Yes, well, I suppose it does although I find it all less satisfying when the bounds of reality are so blithly disregarded. The wind-up for this story is long. For a book named after a character, we don’t really meet him until page 100. Some of tangent/threads were pretty tedious. I don’t think I’ll reread The Long Dark Tea-Time of the Soul, and I rather worry that I will no longer like The Hitchhiker’s Guide to the Galaxy either.
As for similarities to Mr. Luck? Not too much. Our system is based on manipulating the unobserved/unobservable. It’s a "quantum" principle, but we’re using it in a perhaps more obtuse manner than Dirk’s understanding of the inter-connectivity of everything (I imagine that if Adams wrote this novel now instead of 20 years ago, entanglement would come up more).
Watched the first season of Slings and Arrows. Good stuff, if you like theater comedy and Shakespeare. Also, Paul Gross seems to have one of those faces I do not recognize from role to role.
