Panorama , say, probing fiscal watchdog is comparatively offensive (8)

I believe the answer is:

obscener

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

'comparatively offensive' is the definition.
Both the answer and definition are comparative adjectives. Maybe there's a link between them I don't understand?

'panorama say probing fiscal watchdog' is the wordplay.
I cannot really see how this works, but
'panorama' could be 'scene' (synonyms) and 'scene' is present in the answer.
This explanation may well be incorrect...

'is' acts as a link.

Can you help me to learn more?
