I enjoyed this for the Martian angle and Heineline's pellucid blend of liberalism and philosophy. I know the science fiction community is rather odd as a rule, but quite why this novel is so holy, I sort of fail to Grok. I've read better Heinleins. This was very enjoyable, don't get me wrong, but sometimes I do think all the hype over a work can place it on a pedestal it may struggle to overcome
