Unrestrained and violent action amazingly handled -- no doubt by director, ultimately (5-3-7)

I believe the answer is:

blood and thunder

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

'unrestrained and violent action' is the definition.
I can't judge whether this defines the answer.

'amazingly handled no doubt by director ultimately' is the wordplay.
'amazingly' is an anagram indicator.
'by' means one lot of letters go next to another.
'ultimately' suggests the final letters.
The final letter of 'director' is 'r'.
'handled'+'no'+'doubt'='handlednodoubt'
'handlednodoubt' anagrammed gives 'bloodandthunde'.
'bloodandthunde'+'r'='BLOOD-AND-THUNDER'

Can you help me to learn more?

(Other definitions for blood and thunder that I've seen before include "melodramatic" , "Sensational" , "melodrama" .)
