Ppt slides...do theymake my students lazy?

As my university provides facilities in the classrooms that enable us, lecturers, to use technology, I feel very lucky that it is easy for me to teach my students by delivering the teaching materials with Powerpoint (ppt) slides. Most of the materials are conveyed through slides and there is an unwritten convention that each lecturer must use ppt slides when teaching. The lecturers then upload the ppt slides containing teaching materials in our intranet system where students can download them with the hope that they can read the materials before going to the class.
This way of obtaining slides from our intranet causes two sides: positive and negative. The positive side is that students are ready to join the class and understand (although not fully understand) the materials they are going to have in the class. The negative side is that students are lazy to take notes as they take for granted that they have enough information on the materials deriving from the slides.
I feel that the way of uploading ppt slides to the intranet is good but we must watch our students very closely whether they have enough information on what we have delivered to them.I don't mean that we will treat them as children that must be spoon-fed and warned each time they do something in the classroom but this is just a matter of ensuring ourselves as lecturers that students have good understanding of the materials.
Concerning the appearance of the slides, so far, I have created some slides containing teaching materials. I look at the topic that I deliver to my students whether this topic is serious (meaning that theories are dominating the subject) or maybe the topic is 'light'(meaning that there must be more practices than theories). If theories dominate the subject, I try to create slides as interesting as possible as students will get bored very easily if they must look at writings on the slide without pictures or hyperlinks. But if the subject is discussing some 'light' topic then, I just need to add a dash of pictures, and other hyperlinks to the slides as the subject itself is interesting.
I also often ask my students to present their projects, papers, and findings in front of the class using ppt slides. It seems that they are eager to do so as they can express themselves through the slides. And I also find out that my students like to browse the internet to get the most interesting ppt slide template or backgrounds. And I also watch very closely that they seldom use sound or letter animation as they want to deliver the topic as clear as possible with the exact time of presentation without the disturbance of sound, animation, and animated letters that will distract attention.
Well, I think that ppt slides will not make my students lazy in taking notes or listening to my explanation but they are more attracted to the materials IF I present them in a good, expressive, and interesting way using ppt slides.
