"Whenever a spin-off of a popular series is announced, many fans begin to worry about the quality of said spin-off. Could said spin-off overshadow the original work or could it be a terrible cash-grab by the studio? No one knows and it is always a risky endeavor. A Certain Scientific Railgun is a spin-off form the stellar A Certain Magical Index series and now that FUNimation has released the first part of Season 1 in North America, does Railgun offer a great experience on its own?"
