I assume we all know something about Dragon Ball, so my job here is to help you decide whether or not you should read this iteration of the manga.
One thing we all know about Dragon Ball is that everything takes forever—for better or worse. Wouldn't it be nice if were to be shorter, more to the point, and in color? Well, that is what Dragon Ball SD is all about. I should point out, however, that it is not as good as it sounds: It is aimed at children (more so than the original), with heavy use of the super deformed art style, and a really, really condensed storyline.
Even with its fast-paced, light story, I would still recommend all Dragon Ball fans to read this; it is, after all, a breath of fresh air for the Dragon Ball franchise.
But, if you are not that familiar with Dragon Ball, I am sure there are better things to read, because to you, this is nothing more than a ''quick'' introduction.
