A brilliant mentor of mine(who went to MIT for his undergraduate and graduate degrees if that matters to anyone) used to decry lectures that were too mathematical rather than being more intuitive. I feel the same as it's far easier to develop the mathematics after having been given only the intuition than to develop intuition after having been given only the mathematics. Obviously there should be a balance but I prefer that my graduate mathematics courses err on the side of being too intuitive rather than too mathematical because I can generally figure out the maths on my own after the lecture.
