Barnett is quite different from Stephen Fry in that he is a protestant scholar rather than an atheist journalist. I'm sure whatever he wrote is much stronger and more difficult to pick apart than the things Fry says. I would say the best way to approach books like this, if you are truly curious about knowing what they have to say, is by balancing it out with a good Catholic apologetic source.
My guess on how Barnett could be different is what I've heard from most Protestants - that Catholics 'make up teachings' that aren't 'in the Bible', as if the Bible composed every single religious belief in it. They don't share our belief that all teachings are (and should be) consistent with scripture, but they are not solely contained in Scripture.
Also, I'd be weary of the Catholic author Garry Wills. Though I haven't read "Why I am a Catholic", I heard reviews that his ideas were quite un-Catholic. Unfortunately, I found this to be true upon reading "What Jesus Meant", which I had bought without looking at reviews first. This author claims to be Catholic, but is against the clergy, the Pope, organized religion, 'exclusion' of women from the priesthood, and a slew of other Catholic teachings (he seriously uses the phrase "St. Judas" at one part).
My advice before buying Catholic books - do a thorough review from trusted sources (I checked CAF after the fact, and it confirmed what I had already experienced). As for anti-Catholic sources, I don't much see the point in reading those when one can simply turn on any popular television station and just wait for some irreverent comment.
