Nice photos everyone and a nice discussion.
Bokeh isn't quite defined only as DOF, and as noted is quite subjective. It's more of the 'quality' of the background/foreground that is out of focus and varies by lenses, even in the same focal length, and can vary, by quality level, in f-stop selected by distance from lenses to subject as delineated from the background/foreground by their distance(s) to the subject and the quality of 'out of focus' objects.
I would suggest that a slower f1.8 might be a more economical and smarter lens in some focal lengths for most photographers that faster f1.4 or f1.2s.
I use a Micro 60mm lens at f2.8 or a bump down, too, and think it is a nice lens.
The 50mm f1.8 is a good cheap lens and works great at at wide or a bump down as well.
But stopping the 50mm down to f8 keeps a scene sharp when you want it.
and you can cheat and use the same lens at f2.8 and the same photo for another display of the same actor for another play ;-)
Inside, and with the room to work, you can stop down with a 85mm to f4 for a really sharp photo with adequate DOF for both eyes, and significant sharpness to tell a decent story.
or outside wide open at f1.8 at a distance, to tell another story.
I have had the more expensive lenses (and in some cases my organizations have had them) and they were nice to use because they were bright and easier to focus and see the subject, but I don't really think they produced significantly better results for the cost.
From habit I tend to check my DOF and usually will stop down a bit to err on the side of more 'in focus' than out.
Naturally, creative focus within the 50mm lens, at f2.8, we could highlight a cast member.
From all this, I suppose that I'm suggesting that there's a lot of options you should consider when choosing lenses and apertures. I have only two thumbs, and few rules to use with them. Like a goose, I wake in a new world every day. We're shooting a lobby display this week and I hope I come up with something, soon.
Bokeh is another matter and subjective. I can't address that, you'll have to come to grips with that on your own.
My best to all,
