The theme generally dictates the power which is why I'm saying what I'm saying. I'm not disagreeing with the power his bankai has I'm disagreeing with the theme you're saying it has (and to be honest I'm not sure what theme you're going with either).

If the theme you're going with is "Surgery" then I ask: What/how does both Urahara's shikai and bankai correlate to this theme ?

If the theme you're going with is "molecular manipulation" then I say: that feels like a cop-out; something as powerful as molecular manipulation is so overwhelmingly broad in terms of applications that saying its powered down version is merely "energy manipulation" is a bit cheap for me. Even saying that, I can't see how energy manipulation and molecular manipulation are even related in the first place; I can understand if you said, "Molecular Manipulation expands to become Energy Manipulation" because in works like this energy is pretty much the basis of everything (i.e. if you can control molecules then you can control the energy that permeates and powers molecules etc), but the other way round I'm just struggling to buy it.

Now I'm not saying that the bankai itself is bad, because I actually quite like its design and some of its applications. I just have a problem with how the powers/themes of shikai and bankai for this zanpakutō are linked... no zanpakutō has a shikai and bankai that have unrelated abilities...
