This is absolutely not were you should start with Heinlein whatsoever.

Usually in his works, he walks a very fine line between beeing a creepy old man and telling a compelling story with interesting ideas. This, however, is pure creepy old man without any ideas worth exploring beyond the basic premise. The whole novel is wish fullfilment: the old protagonist gets a new hot female body and there is little page time that isn't spend on him hitting on everyone and beeing supported to do that by everyone else. It reads like embarrising and cheap porn without any of the explicit scenes.

It is still sometimes entertaining in the same way really bad movies can be entertaining, that's why it still gets 2 stars. Also, I just really like Heinlein's style and how, in a lot of his works I've read, his main cast is just really harmonious.

I'm glad I've read this shit show so now I can relate more to what is basically the criticsm to every later work of his and know how bad it can get.
