I think all the efforts to make FT more intuitive are necessary because representation of signals in terms of complex numbers is a tricky abstraction. It's definitely worth taking the time to get comfortable with the idea of representing a signal in the complex plane without trying to understand the FT at the same time. Then all the spinning-around-a-pole verbiage makes a lot more sense.
