Sin pena ni gloria

Sin pena ni gloria
 

who can give me some equivalents for this stock phrase in ENglish?

Can you give me an example of what it means and how you would use it in a sentence? I don't recall having heard this phrase before. A bit of research shows that it doesn't literally mean "without shame or glory". The main meaning I found was more like unimportant, unnoticed, completely normal, average etc.

La obra de teatro pasó por los escenarios sin pena ni gloria.
The play was incredibly average.

La película pasará a la historia sin pena ni gloria.
It was a completely forgettable movie.

Excellent examples, also for books or entertainment shows.

neither hot nor cold
so so (this term is also used among Latinamericans)

That´s a differente one. No dar ni frío ni calor, no hacer ni fu ni fa, when something is indifferent to you. Is there a saying in English?
