The problem for me was that while there were various relationships throughout the story, it wasn't focused on them alone, and the story was still about the band and the reunion and stuff, but then at the end the focus changes to be more on one specific couple (which I won't spoil you for) and I was left feeling like it was unbalanced and that the real story was left hanging while it went off on this shippy tangent (which happens fairly often in plotty slash fics, unfortunately; the outside plot goes by the wayside when the romance is resolved).
