A Certain Scientific Railgun (2009– )

There was the potential for serious depth in this spin off series and it flirts with it in the first season, but in the end seems to shy away from taking it to the next level, because it's trying to maintain the upbeat tempo.

The first two seasons are overall enjoyable and worth watching but I'm undecided on the current third season. It seems weaker which is a shame as it deals with a "foe" and the associated powers that could go down a dark and thought provoking path
