While I would agree that his interpretation of Wittgenstein on following a rule and private language, is wrong as such, i.e. as an interpretation, it is definitely very interesting and thought provoking stuff. It is good philosophy and bears good witness to the creative genius of Kripke.
the stuff he calls the "frege-russel theory of names" is even more egregious than his take on wittgenstein.
to be fair, i don't believe his "take on wittgenstein" is exegetical anyway. he's putting forward his own (interesting!) plus/quus argument. kripkenstein is worth reading in its own right; if you care enough to get wittgenstein right in the first place you shouldn't really be looking to kripke's writing to get there.
and of course, "the frege-russell picture of names" is just a straw man to propel his argument forward in N&N. he's really talking to/about searle there, and most people who are going to read N&N know that. but the stuff he says is still wildly inaccurate if you take it at face value.
(not that frege's views on sense and reference are all that clear in the first place, but they weren't the nonsense that frege (or searle!) attribute to him)
