Despite the ad campaign I only just stumbled across this by accident the other day, read up the storyline and watched the trailer.
It looks good, an interesting social commentary in a science-fiction film, and quite ironic (although perhaps intentionally so?) that it was chosen to be filmed in South Africa.
Regards Tarantino, there are some of his I like, Kill Bill 1 and 2 comes to mind, primarily for his cinematography, the way he sets up shots and filters, it's very artistic and also usually very bloody
Eastwood in the westerns, classic stuff, another classic =
