In my opinion -- and I know this is subjective -- that's a linear presentation. And so I would say no, that's not the kind of presentation I'm looking for. The content is arranged in a line, in some arbitrary order.

The "vertical slides" add a bit of hierarchy, but again, I don't feel that they add any non-linearity to the presentation.

Now, if say the 15th slide referred back to some content in the 8th, or if the 3rd-6th slides were all interrelated -- and this structure was reflected in the structure of the presentation -- then I would be enthusiastic.

So tl,dr; I agree with you -- I dislike these presentations.
