The moment Goku become a super saiyan for the first time, he became one of the most badass superheroes in both japanese and american comics, dragonball z's badass got turned up a notch when he turned super saiyan all you kept hearing about during the saiyan saga were talks and rumors about a "super saiyan"................however when every other saiyan and their grandmother could become one, it lost all badass quality's. I also hated the super saiyan 2 3 and 4 forms. In my opinion goku should have been the ONLY saiyan capable of going super and that the basic super saiyan form is the ONLY form and that Goku trained it to be just as powerful as a super saiyan form 3 would be, that makes Goku much more awesome and also makes the super saiyan form that much more special, in which Goku rarely uses the form but only when he really needs to, so that everytime he changes, the audience would know this was going to be epic if the villain was actually strong enough to take on a super saiyan. Vegeta said it best "its like there is a sale on super saiyans" (or something like that). Goku would be the only super saiyan, HOWEVER, during the cell saga(in my opinion when the series should have ended) when Goku takes on cell in his super saiyan form and fails to do so. Gohan would face Cell in his regular form, in which point the audience would think If "Super saiyan Goku cant take cell on, theres no way Gohan can !!" then when Goku dies in front of Gohans eyes, much like how Goku turned super saiyan out of rage, Gohan turns super saiyan for the very first time, and now finally another super saiyan, if all of you can recall, ever since the saiyan saga there was talk of gohans "hidden power" and that he could possibly be stronger than goku, and now in the cell saga that hidden power reveals itself and Gohan has actually surpassed Goku.
