If you are an EXO die hard fan, you can watch this. But don't expect too much of a story. It is just so simple, naive if you are to be critical. There is a glimpse of a potential good drama if the characters were given more depth. Supporting cast was wasted. Good that they did not drag a very simple story further with fillers, and wrap the whole thing up in few episodes. But Choco Bank could be better a romance movie, still with more intensity for the story line. Again, you must be an EXO loyal fan to watch this one.
