Considering they knew going in they would have one chance to sell people on why they should watch the show before it went behind a pay wall, I'd say it is fair to condemn them for not making sure the Klingons were not boring from the get go.
Ultimately though I think that is my problem with the show. It actually wasn't that bad unless you go in determined to hate it but at the same time it wasn't good enough I'd pay extra money to keep watching it.
The 'look' change wasn't what killed it for me, it was two things:
1. They made their antagonists
boring. The 'new look' could've been great-if it didn't come off so completely wooden once the picture was in motion, if these nu-Klingons weren't so lemming-like in group scenes, if they weren't
all moving so stiffly in every motion scene, if they had the ability to have anything but ONE expression (the one molded into the mask).
boring.
2. Burnham wasn't such an
idiot. by the third time I wanted to scream "are you stupid?" at the screen (she was doing the spacewalk and was out of contact, so decided to take a stroll on the object. jesus, she hadn't even one-shotted the Klingon yet...)
it's like they spent the entire writing budget on those amazing visuals in space, and the entire direction budget to hire Michelle Yeoh as the galaxy's most expensive redshirt.
by the end of the first hour, I didn't
want the second...but my roomies did.
as for the klingons in ep. 2 'acting just like tng" that's complete and utter horse shit. They were identically as wooden, and nearly identical in their expressionless, emotion-less, wooden delivery of lines.
