Visual retcons is one thing.
But Discovery goes leaps and bounds beyond that. Holograms in 2256? Even the Prometheus of the 2370s was NEW with the ability to project holograms outside the Holodeck or Sickbay.
Those were simple holograms; projections of people communicating in real time - low definition images with obvious imperfections. We have similar technology today (have you ever seen the Tupac hologram?
). The holographic images in Discovery were nothing like the holograms of TNG/DS9/Voyager that had full on sentience and were visually indistinguishable from a real person.
Window as Viewscreen? Really?!? Again with the bullshit JJverse
It pretty clear that they were around in the prime universe as well before the timeline split between it and the JJ-verse. The Shenzhou is said to be an older ship as well, possibly from the Kelvin's era. The Frankin (from Beyond), an Enterprise-era ship, had them too.
Then there's the Klingon ships, which bear little or no resemblance to TOS D7s
C'mon dude, we're only two episodes in; we know next to nothing about those ships - for all we know they're just as old as the sarcophagus ship or simply private, civilian vessels owned by each house's family, not military vessels.
Klingons with Cloaking Devices? Romulans using Cloaks was NEW in 2260s
That cloak was destroyed before it could be spread. The Enterprise novels explained the cloaks in "Minefield" as being defective due to them taking power antimatter containment. Since the Klingon's cloak was destroyed, we know nothing about if that would be a problem for them too; but no matter what, the technology died when that ship blew up.
Starfleet protocols of 2370s, says you always travel at minimum 2 people
Exactly, the
2370s, this is the
2250s. In Kirk's era it was common for the captain and first officer to go on away missions together; we saw Kirk run off alone several times and Archer as well a century earlier. Protocols change.
Are there no Redshirts in this era?
I will concede we definitely need redshirt console explosion death.
You're entitled to your opinion, but I swear I'm getting flashbacks to the kind of nitpicking that ended up killing Enterprise right when it was getting good - partially the showrunners fault for going in the prequel direction, but isn't there room for fans to meet in the middle sometimes (especially so early in the series life)? This is our first series in 12 years and we're only two episodes in - and Trek spinoffs are well known for having problems in their first two seasons (compare TNG, DS9, Voyager, and Enterprise's first two years to their later ones for reference).
