It's a favourite of mine too.
I had it in my top 20 the first time I made one, but recently it dropped out of it
A great Garko, great Camaso and a short but noticed appearance of Fernando himself (he dies miserably)
I have only watched it once and wanted to watch it for a second time before I review it, and every time some other title took my attention
The problem may be that it's considered to be a twin movie with 10.000 dollari per un massacro (different director but same cast), and most people prefer that movie (so it gets most attention)
I prefer this one
