Of course I can see why its run of the mill for you- there's certainly not much depth to the story/characters and nothing particularly notable in the way of analysis.
Though for me, where it rises above the norm is in how the movie maintains a very watchable pace without inserting the usual boring and time filling scenes. The running time comes in just under 1.5 hours, which is great- a movie of this character should aim for as short a time possible IMO, as there's no need to extend anything... just tell it straight and present a flow of the kinds of scenes we all came for without making us suffer through the boring filler. Son of Django does just that, and if you enjoy Fidani like westerns on their own terms, then I whole fistedly recommend this one.
Spaghettis come mostly in two flavors for me. Ones like Son of Django and then the higher standard fare like Leone. This makes for what I assume looks pretty odd when it comes to my ratings, as I can rate something like Son of Django highly and it may sit next to another film which is technically much better. But for me they are almost two different kinds of films and I do not watch them in the same way. Its like comparing a John Wayne film to a spaghetti- they occupy two different worlds and the comparison is not particularly useful.
As a last note, Son of Django features Guy Madison as a six shooter wielding priest, and this always serves for brownie points from me. Pretty cool that Wild East released this as a double feature with Reverendo Colt, also featuring Guy Madison as a anti-priest. Will have to pick that release up when I get a chance.
Getting a copy now, will be watching soon
