Using Power Point for lectures

Recently I've realized that teachers are cluing into the fact that students by a variety of means i.e. listening, seeing, and doing... And further more, these teachers are attempting to incorporate appeal to the variety of learners by using power point (along with the lecture). I understand the notion that seeing paired with listening benefits the learner. However, I don't think that just because we see the words up on the power point, we are better learning the content of the lecture. This post may seem negative and a bit like I'm complaing. But, it's more just me trying to decipher (as a student who will soon be a teacher) whether or not using power point presentations along with lectures are beneficial to the students. In analyzing myself in the classroom, I know that just becuase the teacher has added a power point with some annimations and cute pictures, I am not further engaged in the lesson. It may just be me, but as a future teacher I would like to know if the time spent preparing the slide show is worth it?
