Query: Like plot, like protagonist.

I'm not one to chastise a story for being outdated. And I have to admit, this particular book does reflect its years with dignity in a conceptual context. Unfortunately, the plot never really ascends to its full potential. Like its hero in the beginning, the book is a well of possibilities with no purpose to drive it to greatness. Also, inconsistencies and non-researched science (the light side of the moon always faces the sun...there is no 14-day swap in light and darkness) hamper the story to anyone who can recall the last few pages or who's spent ten seconds in a high-school physics class. Morally, the book runs a tad preachy (don't abandon faith for it shall set you free) and ideologically it never really takes off. Recommendation: read Welles...fat dead men are always a kick.
