Nobody opening - it's a disappointing affair (3-5)

Ross

I believe the answer is:

non-event

'a disappointing affair' is the definition.
(I've seen this before)

'nobody opening' is the wordplay.
'nobody' becomes 'none' (I've seen this before).
'opening' becomes 'vent' (vent is a kind of opening).
'none'+'vent'='NON-EVENT'

'it's' is the link.

(Another definition for non-event that I've seen is " disappointing affair".)

I've seen this clue in The Telegraph.
