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

'sensational?' is the definition.
(I've seen this in another clue)

'carp at clues made badly' is the wordplay.

But, I'm not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for spectacular that I've seen before include "really striking" , "Sensational in appearance" , "Lavish production" , "Splendid" , "Extravaganza" .)

I've seen this clue in The Telegraph.
