While I agree.. Any decent lens review takes into consideration the "quality" and properties of the lens' bokeh... it's quite common for a lens to drop lots of points and be considered less desirable just because it sucks at a single thing - be it bokeh, barrel distortion, or vignetting (etc). The iOS software *needs* to make attractive bokeh, even if it doesn't emulate the circles/shapes involved in trad lenses.. it has to eventually not look artificial - so it that sense it still has a way to go.

it (sometimes) looks fake because of the non smooth gradients and haloing.
Given bikes properties are a major consideration when choosing a lens it doesn't surprise me a lot of photographers are a bit dismissive of the effect as it stands.
It's still very cool though and I'm happy to see it.
