I went there once, I think in 1988. To me it was a nightmare, aesthetically and otherwise. The art of the monument was “not even as good as fascism.” (Various Soviet-era memorials are far superior as well.) I am not into the whole cancelling thing, but I didn’t feel I needed to pay additional homage to a bunch of well-known presidents. The surrounding food scene appeared quite mediocre, although probably that has improved. Overall it was crowded, tacky, and unpleasant, with absolutely nothing of value to do.
The main value of the scene was to liberate space and ease congestion in other parts of the universe, so I certainly hope they never abolish it.
