Rukia's Execution differed in that there was a clear and defined threat. If they fail to stop her execution she would be destroyed. There is so little information regarding the Soul Fragments that having them be the focus of the plot is strange to say the least. Their existence has no ill consequences, so Soul Society getting up in arms about them makes little sense.

I'd advise that the Soul Fragments be given definitive properties that make their capture/destruction a top priority. I had a discussion with Chrono regarding Yhwach, specifically his role because I find his entire existence a bit of a contradiction within the Bleachverse. But some good points were brought up, namely the fact that Yhwach as the son of the Soul King is an extension of the Soul Kings function.

Whereas the Soul King was the lynchpin for the cycle of reincarnation, Yhwach too served some purpose. When he acquired the power of Migi, and absorbed the power of the Soul King, he inadvertantly became that center. With him dead and his Soul Fragments scattered across the world, it introduces some potential key points.

The first is that, the Soul Fragments are necessary for the continued stability of the wheel of reincarnation, and while it has remained largely stable, there is degradation. Every year fewer souls are returned to life, birth rates are declining and Soul Society is seeing a steady loss in its population. Furthermore with the powers distributed as they are, certain parts of the world are being affected simply by the proximity of a Soul Fragments. Regions are experiencing unsual growth, the number of spiritually aware humans are skyrocketing, and perhaps the boundary between the physical world and the spiritual world is eroding. People may cross the road and end up in Soul Society and vice versa.

Establishing a clear and present danger is key to really hitting home the danger of letting the Soul Fragments just be left unchecked. Individuals who possess Soul Fragments may be experiencing strange things, may become central to certain key events, astrological events, or what have you. Hell maybe the Lost City of Atlantis aint so lost anymore. Maybe Hueco Mundo is encroaching in certain parts causing Hollow activity to spike exponentially.

This give us the authors things to do, plot lines to play with, all while keeping the focus centered on the Soul Fragments. Tear it down, give it thought, whatever you do, just clearly outline what would happen if the Soul Fragments are not handled in a timely manner. As you mentioned before Rukia's Execution was a big focus, but that was precisely because it was so clearly defined.
