there are many things that in theory have a particular point but that when put in practice most often do not have any point at all - in such cases opinion seems to divide between those who complain that the people who put things in practice do so incorrectly and those who feel that if the practice when implemented tends to be wrong then it is the fault of the theory itself.
That is not the theory, that is the goal. Sprint reviews have a goal of identifying something as being shit and then removing it, they have a theory as to how this will be achieved which is the sprint review process.

I personally hold with the latter view.
