The school is not that important--the instructor is the important thing. Your experience, unfortunately, is not that uncommon.
Many pilots look at the CFI job as time building until they have enough hours to fly "real" airplanes.
Try to find an "old fart" instructor, like a retired airline or military pilot who is doing the job because he likes it. You will learn more faster than you would from a new CFI that got his CFI last week.
