(Wikipedia) Totalitarianism is a form of government and a political system that prohibits all opposition parties, outlaws individual and group opposition to the state and its claims, and exercises an extremely high if not complete degree of control and regulation over public and private life. It is regarded as the most extreme and complete form of authoritarianism.
So that would only be ‘good’ from the point of view of your totalitarian ruler themselves. It doesn’t say anything about whether it is good or bad for anyone else. And - critically - only good even for them as long as your ruler was actually competent enough to get to where they wanted to get to in the most efficient way. If they were not going to be taking opposing views into account they would have to be universal experts.
