vox: Very little else about the [Star Trek] Discovery is. by Aja Romano
'The graphics and visuals feel modern, but still very much in keeping with the aesthetic of previous Trek series, in particular Voyager and Deep Space Nine. Alongside new starship officers, we see familiar faces, including Vulcans — specifically Spock’s dad, Sarek, and apparently a young Spock — Romulans, and Klingons. The Klingons, at least, seem to have gotten an upgrade — they’re more warlike and menacing than ever, and we get a rare glimpse at what seems to be a royal Klingon burial ceremony.
'What gets short shrift in this trailer is the series’ overarching plot; but given that the Federation’s shaky forging of alliances with the Klingons is a crucial part of Trek history, and their prominence in the trailer, it’s likely that their early conflict will drive the story. In any case, seeing the Klingons in all their combative glory feels a bit like coming home for Trek fans.'
