This is how I would rank Hill's serious
1. Viva Django ( his most serious role, in my opinion)
2. God Forgives I don't
3. Ace High
4. Boot Hill
None of the The trinity films, nor my name is nobody, or Little Rita of the west, or A genius two partners and a dupe were super serious, and I find Hill doing good work but not his best. Little Rita of the west is one of the worst spaghetti westerns ever made.
