What do you mean no originality = bad story, clefo?
This story is a parody. There are lots of incredible movies out there that do exactly what you seem to hate. That list includes Monty Python and the Holy Grail and Spaceballs, two of my favorite movies of all time.
By borrowing from the story yet changing it to make it fit the boards, they are making a parody of LOTR. Parodies are often times funny.
Peace is but a shadow of death,
Desperate to forget its painful past.
And though we hope for promising years,
After shedding a thousand tears,
Yesterday's sorrow constantly nears.
Unless a grain of wheat falls to the ground and dies it remains alone.
