I believe the answer is:

satanic

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

'bad shape' is the definition.
'satanic' can be an answer for 'bad' (I've seen this before). I'm unsure of the 'shape' bit.

'cast in a very' is the wordplay.
'cast in a' anagrams to 'SATANIC'.
But, I'm unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for satanic that I've seen before include "Hellish" , "Fiendish" , "Like the Devil" , "Like hell it is" , "Devilish, like Blake's mills" .)

I've seen this clue in The Irish News and The Globe and Mail.
