I removed a small star because of the fantastic too present for my taste, and touch is to the detriment of science, sf and the unlikelihood.
I removed by against a huge star because of Marvin who literally disappeared. not a single allusion to the character for me was central both in terms of history than humor. and there finished laughing because Eoin Colfer has no excuse because it has still an improbability generator INFINITE. This shows his world skimpy compared to that limitless and totally improbable Douglas Adams.
Eoin, thank you anyway; I look forward H2G2 7. And with Marvin
