You're right, BB. It's not a good thing at all when only one party controls the whole show. The same applies in Canada. The best governments we've ever had here, in my opinion, were our minority governments...the reason being, we have a multi-party system, so in our system a minority government means that the ruling party must reach accomodations with at least one other sitting party in order have a working majority to pass any particular piece of legislation.

That results in more than one "voice", so to speak, having a real say in the process...and that results in better legislation and less corruption of the political process by special interest groups.

A single party-dominated government is effectively a temporary dictatorship of that one viewpoint over all others. That does not lead to good governance, it leads to arrogance and misuse of power.
