Great minds think alike?

Every now and then you stumble upon two campaigns which have the same idea and the same creative solution or display for that idea. So, it can be that great minds think a like or maybe the clique is just a bit too much of a clique. In this case I am talking about the new two TV campaigns running at the same time. The first that went on air is Coca Cola Diet and the other of course is Pelephone. Now, I am not hinting in any way that first in is the original, I am just throwing in a thought. One other question is: should it (the second campaign aired) go on air as scheduled and take a chance of becoming more of the same and maybe even being perceived as a copy cat? Or should they go back to the drawing board? The truth is (well my truth) that both are OK, and I chose OK for a reason. I don't find both exceptionally original, but still, both are well made and both interpreted the same idea in different ways. Pelephone kept it's usual line of a Dr. Seuss utopia and colorful world and Coca Cola on the other hand stayed with it's interpretation of an X-generation MTV clip. Which one is better and which one will effect it's target audience more and give the client it's value for money? You will be the judge of that.
