Hmmm.
I find the bokeh par for the course for a sharp 35mm with the main issue being complex highly defined backgrounds with high contrast and probably at mid to longer distances, like twigs, foliage etc. In other scenarios the bokeh can IMO be quite nice for a 35mm. 35mm f1.8 is not going to give the bokeh you'd get from either a 35mm f1.4 or a 50mm f1.8.
Some reviewers cover this quite well. Here's a review with examples. I agree with just about everything this guy says.
Review of the Sony FE 35mm F1.8 which covers real world use as well as in-depth technical analysis and contains many full resolution samples.

"The Sony FE 1.8/35 is a very well balanced lens. It is very sharp, for most applications. It has pleasant bokeh at short to medium distances and becomes a bit harsher at longer distances but so does almost any competing 35mm. In general it corrects all aberrations good enough so that you need to push it for them to become distracting. At the same time it handles well thanks to quick AF, ok MF and useful buttons without any quirks. And the 1.8/35 manages all that while being rather small and significantly lighter than most competing E-mount lenses. Therefore I would say that the Sony 1.8/35 will easily keep up with most photographer’s expectations. Only the price seems to be maybe $100 too high at the moment and I hope that we will see it come down a bit with time."
There's a huge Sony 35mm f1.8 thread at Fred Miranda.
I don't find CA to be too much of an issue. Geeks will see it in backlit high contrast situations though.
A Manny review.
