Therefore, having an identical twin is not bad (2-2)

Ross

I believe the answer is:

so-so

I'm a little stuck... Click here to teach me more about this clue!

'not bad' is the definition.
(I've seen this before)

'therefore having an identical twin' is the wordplay.
I cannot quite understand how this works, but
'therefore' could be 'so' ('so' can mean 'consequently' or 'therefore') and 'so' is found within the answer.
The remaining letters 'so' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'is' is the link.

Can you help me to learn more?

(Other definitions for so-so that I've seen before include "Indifferently good" , "Nothing to write home about" , "Barely passable" , "OK, but nothing special" , "Of middling quality" .)
