When discussing City Hall I think it's always important to figure out whether the person arguing for its demolition is coming from a "I hate the building itself" or an "I hate the building because of the plaza". Architecturally I think the building itself is interesting and worth keeping.
Ideally I think City Hall the building can be "fixed" by a good architecture team that understands Brutalism and also how to retrofit buildings to make them more engaging. That's going to be hard to find and expensive, but doable if preservation is desired. Fixing the situation on Congress would be a massive improvement.
As for the Plaza. I'd build over a chunk of it while leaving a wedge of sorts that allowed a view coming up Tremont.
