I'd say ditching lectures is a bit extreme. It's really all down to the lecturer themselves and how the students participate. If you don't want to go to the lecture and rely on reading the PowerPoint presentation from home then go ahead, but usually the lecturer will add to what's in his/hers notes with information that's pretty crucial.
Lecturers have to be good at presenting the information; countless times I've seen lecture slides with absolutely abhorrent colour schemes such as black/yellow and yellow/red and it's just not nice to read.
Lectures are a two way thing; the student has to engage, and any student that doesn't know how to take notes needs to look at themselves. It's a pretty crucial skill to have in life. The lecturer has to make it interesting for the student, and make the information easy to digest.
