All things considered, there's not much to say about "Bring it on Ghost". A very easy story to follow (to the point it's actually not really creative nor original in any way) surrounded by young, talented actors, provides an entertaining show that would, subtetly, make its way in your mind.
To achieve this, there's not so much involved (essentially, this drama rhythm is quite good, if you except the useless yet funny comic duo scenes) yet it proves there was some work from the writers/director to carefully craft this show into something valuable for the viewers.
So while there's not much to expect from this drama, there's a very good chance you're going to spend a good and entertaining moment, and if that's all it was ever needed for you, this show is a must-see.
