Not a fan of Dakota Johnson, but the rest of the cast look fine. Sorry to disappoint (only watched this trailer) it is nowhere near the level of Tarantino in style or dialog. It is more reminiscent of Hateful 8 than Pulp Fiction and while Dusk till Dawn is set overnight in Titty Twister, that is Rodriguez rather than Tarantino (although he did write and star), is more a Grindhouse than a Film Noir.
There are any number of similar movies based in Motels and Hotels with a disparate bunch who have unsuspecting connections and this does not appear to tread any new territory. It may well sound fine, but I don't think it will be beating a hasty path into my collection anytime soon. Perhaps from the bargain bin or Netflix.
I have two basic types of movies. The first is the worthy's or epics, things like Tarantino, some Clint Eastwood, Chris Nolan, Orson Wells and a number of other. These are films I love, but I don't re-watch them often lest they lose their impact. Then there is the second group. Turn off the little grey cells and just enjoy it, like Star Wars, Underworld, Horror, Sci Fi, Action, Comedy, etc.. This is bulk of the collection and I watch these all the time and whenever it takes my fancy. End Times at the EL Royale does not rise to the first and does not look interesting enough to make the second. When you have to engage the brain and follow the plot twists, I tend to be a lot more critical of the end result.
Of late I am working my way through the entire Bond collection which have all been remastered. They look beautiful, sound is ok on the early ones, but it's just glorious hokum. It sexist, certainly not PC, even a bit questionable in places and some of the sets are a wobbly, but it is a lot of fun.
