Goes too far past -- really? (8,2)

I believe the answer is:

overdoes it

'goes too far' is the definition.
(to overdo it is to go too far)

'past really?' is the wordplay.
'past' becomes 'over' (I've seen this in another clue).
'really?' becomes 'does it' (does it really?).
'over'+'doesit'='OVERDOES IT'

I've seen this clue in The Telegraph.
