Yes, Kuhn was full of horse puckey. Not only doesn't his book describe science outside of physics at all well, it doesn't even correctly describe 20th-century physics, its ostensible paradigm (using the word correctly now) case.
Years ago I wrote a more detailed takedown in Brother, can you Paradigm?
The only amplification I'd write today is that the shifts between large theoretical models generally (and contrary to Kuhn's claims) go smoothly in physics because test by correct prediction of experimental results is so difficult to argue with. The soft sciences have more trouble setting up repeatable experiments, so it's easier for people to hold on to broken theoretical models.
