in the elegant universe i do not recall him pointing out a whole lot of shortcomings, but he definately did. Usually it is just the way he progresses his book, he just goes chronologically. He starts with what people thought and published, what happened and why it was wrong, then presents another solution that happened in history that works in some aspects but not necessarily all aspects.
In the elegant universe, he gets excited and forgets to look down sometimes when he is sailing in the clouds with string theory, but he oft mentions what is missing from string theory, and many times he will direct the reader towards the future...telling us that it is hopefully only a matter of time before some particle accelerator in the future will detect super partner particles, or that a graviton is found, etc. Withstanding it all, he does not hide the fact that there is no confirmation from string theory in the experimental realm, so that is always nice.
