If you doubt the existence of universal grammar, you should try The Language Instinct as well.
While some linguistic universals definitely exist, and a sufficiently weak version of the language acquisition device idea is pretty much obvious (‘the human brain has the ability to learn human language’), I think Chomsky’s ideas are way too strong. See e.g. Scholz, Barbara C. and Geoffrey K. Pullum (2006) Irrational nativist exuberance
