Cotty, I agree with you in overall sentiment.
The "John Burns effect" is useful when used sparingly, can be very effective as a transition between themes in an orchestrated presentation or when using it to make a particular statement. Overuse of any effects is tiresome and becomes cliché rapidly.
I think this tool, however, is pretty well done and gives options to the presentation creator in a simpler way than other tools I've used for presentations of this sort.
