Feynman himself said that his Lectures were a failure of pedagogy.
Seriously, if you are at all interested in physics - read the lectures and they will, with 100% certainty, deepen your understanding. Even on the most fundamental topics. For instance my entire worldview around the conversation laws changed thanks to those lectures, which in turn ties directly into the nature of energy.
