Very, very meh! (2-2)

I believe the answer is:

so-so

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

'meh' is the definition.
I can't judge whether this defines the answer.

'very very' is the wordplay.
'very' becomes 'so' (both can mean 'extremely').
'very' becomes 'so' (both can mean 'extremely').
'so'+'so'='SO-SO'

Can you help me to learn more?

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

I've seen this clue in The Times.
