True. The way I see it, Kubo could have easily had Aizen quickly turn around and block Ichigo's attack with his sword, or dodge stylishly. To me, his choice of a barrier seemed to be intended to tell us something about Aizen, in this case, that he knows his own weaknesses.

But of course, these arguments can be made over anything. I still see some people calling the Hougyoku implantation deus ex, or worse yet (and I kind of agree with this one), that Wonderweiss just happened to be a tool solely created for dealing with Yamamoto.
