The Cognitive Style of Powerpoint

I agree whole-heartedly with Tufte that powerpoint presentations can be a waste of time and a poor way for people to present information. Though is it our own fault for leaning too heavily on the pre-made templates and reading off the slides themselves that create such awful presentations? Or rather if we used the program merly as a tool for strengthening our speech and use it along with other forms of teaching would it still hurt the information?
