The opening cinematic for Dark Souls III is quite stunning, and you can view it right below. The cinematic style is on par with some very good movies even.
The three-minute intro very succinctly introduces us to the storyline that we'll be following in the very dark and despondent land of Lothric. It's actually quite well constructed and the narrative seems to fulfill the expectations we have for the series. In the trailer you'll see Yhorm the Giant, Farron's Undead Legions, Aldrich Saint of the Deep and even the reclusive Lord of the Profaned Capitol.
