No one wants to believe that the Gra knew what he was doing.
The only Institution that I know of that takes the Gra seriously is the yeshiva Aderet Eliyahu in the Old City of Jerusalem. But that place is more concerned with the general path of the Gra more that the issue of the basic world view of Torah.
Worship of tzadikim seems to have gone unnoticed as being a kind of idolatry. And Idolatry is supposed to be forbidden --or thus I thought.
There were people in the past that thought I had the ability to awaken others towards the authentic Torah. But it seems to me today that I missed the boat somehow.
The cults just grow and grow and the truth is just stomped on more and more.
The idea that Torah is Monotheism is basically expressed by Saadia Gaon and the Rambam and all the rishonim that wrote about the basic world view of Torah. Surprisingly enough the Ari agrees with this. The Ari does not attempt to change the world view of Torah in the slightest. But today these facts are ignored and distorted.
