I had largely the same experience at UC Berkeley, but I wasn't paying tens of thousands of dollars a year in tuition. If I were going to an elite, spendy private school I would expect more in the classroom.
That said, teachers are only a part of the learning experience. I learned a lot of interesting things from the teaching assistants that helped with our large classes, and still more from random older students in our computer labs. One of the advantages of going to a ginormous research university is that there are a lot of really smart people that you can learn from outside of lectures.
