the ad is entertaining and very well thought out and executed. it does well to take a shot at mountain dew ad and plainly on creativity front, can rate it as high as 8 out of 10.
but the problem with sprite ads is that they are always based on some competitors ads. what that does is that it tries to point out weakness in others products. it does not try to concentrate on its own strength. as a result they fail to convince me about their worthiness. so my advice to sprite would be to come out with ads which tell us more about their product along with all this copied stuff.
on the whole not too good or too bad. can rate it at 5 out of 10.
