Defined as a classic but not a great classic

Robinson Crusoe is an enjoyable story. I thought it was a nice plot. Also, Daniel Defoe spoke of survival skills and how Robinson applied the techniques as means necessary for his survival. There was no analyzation of Robinson at least on psychological levels. I can see that he examined himself religiously. That really slowed the book down and became boring in the process. Also, the plot was not strong as the author had too many focuses: the home, the Brazils, the Shipwreck, the wolves incident, the aftermath, etc.. I prefer the introduction and the solitude on an island for the story. The wolves incident completely threw the book out of track. I will call it a nice classic story with a lot of flaws in its novel. It also skims a lot in the novel, not providing a lot of concrete details. When years went by, it didn't really focus on the years, but what happened that seems to happen the same too often. I felt there should be some kind of change annually. One thing I must point out is: How did Robinson took care of himself in regards to the excretion system? How did he go on to take care of the excretion matter?

P.S. I recently visited the new spy museum in Washington D.C.. By coincidence, I was also reading Robinson Crusoe at the same time. I happen to notice the fact that Daniel Defoe was a British spy and was credited being the first to set up the spy espionage network in all of Britain.
