Is the significance of room acoustics overrated?

Don't get me wrong as I realize just how important room acoustics are (I think).

However, let me share some recent experiences:

In our previous home, an audio reviewer/columnist evaulated my system. Very positively I might add. Anyway, upon telling him that my family and I were preparing to relocate to the West coast after his 3 hour evaulation, he responded with "good luck trying to find another room with these acoustics." And I knew exactly what he meant.

Well, we found a home that may have had even better room acoustics but it failed the home inspections. I'm still bummed about that one, but it was on to the next...

We settled on another home and it was either the living room or the family room for my listening room. Because of it's isolation from other rooms (very open floor plan) I selected the family room even though the living room had better acoustics and immediately had an electrician install the dedicated lines there. But this family room has no where near the level of acoustics of my previous room.

Although the same basic sonic characteristics where there in the new room, the bass had peaks and valleys like a rollercoaster. And off-and-on over the next 7 months, I'd move the speakers around trying to locate the best position for overall best performance/best compromise.

Lo and behold about a month ago, I located a position in which the bass peaks and valleys have all but disappearded and overall and in some ways the absolute bass control and response as well as the overall presentation is even better than my previous room.

Of course I can't help but wonder what if I had devoted this kind of attention to speaker placement in my previuos room with better acoustics?

But at the same time, I find it difficult to believe that simply relocating the speakers to an 'optimal' location could cause the interactions with the room's poor acoustics could be minimalized to such a degree.

Therefore, I ask:

Aside from ensuring basic room treatments i.e. thick wall-to-wall carpeting and padding and generally good room demensions/symmetry, etc. is not speaker placement far, far more important?

And lastly, I suppose this thread may offer hope for some that there very well be a better speaker placement to cover a multitude of sins in what should be deemed an otherwise acoustically poor room.
