Congratulations, by making it here you do not pass go, you collect no money, and in fact you feel as if everything Oreimo has built up to is snatched from you like candy from a baby.
To any unfortunate viewers such as myself (didn't listen to the reviews)
If you want any semblance of enjoyment from this otherwise amazing show, Please stop your last ova at 21:10.
I promise you, should you watch past the point of no return you will feel as though you were promised a ride on a roller coaster, only to be taken on a rubber ducky across a pond.
However, I will say this. The finishing touches provided by these 3 OVAs did in fact help to tie up loose ends.
The ending is just atrocious.
