Adrian von Wendt’s review published on Letterboxd:
Django Unchained is about as much a 'Spaghetti Western' as Kill Bill is a Martial Arts film: Quentin Tarantino used the genre as a starting point and merged it with his own vision to create something new. The result is an astonishing epos that transcends the boundaries of the whole Western genre and is both a glorious statement against slavery and great fun.
Of course the similarities with Sergio Corbucci's 1966 classic are rare to the point of being almost nonexistent (apart from the name, the opening titles and a couple of shots there is basically nothing that resembles the original film), although that is quite in line with the genre: Django's success reportedly spawned more than 100 unofficial sequels, many of which have no connection whatsoever to the original apart from the name - so the Tarantino film just continues that tradition.
Fortunately the film doesn't need the connection to a decades old classic to work: It's just a blast to watch, all the way through. Just as it was with Kill Bill you don't need to know the underlying genre to have fun with Django Unchained, but if you do it adds another layer of enjoyment. Awesome.
