>>38851269B2W2 as a part of a gen suffers the same problem with US/UM, there's nothing to unique about them to differentiate from their predecessors in favor of story based lore.
However, the problem with US/UM however it felt like a remake with minor plot differences. Where I can give B2/W2 a pass is that it at least was a sequel to resolve half the shit B/W did in the same way Pokemon Colosseum and Pokemon XD did it but that's about it.
The latter of which might have worked then because those were more or less add-ons for the GBA games but as a generational thing isn't really working out too well.
