I thought Vader was fine, apart from the fact that he wasn’t able to get aboard the Tantive IV. he was able to do that in the OT…
I think it’s important to note that Vader also doesn’t care about the Death Star as has been established in Star Wars and was re-established in Rogue One. Maybe it was less that he couldn’t get to the Rebel and more that he wasn’t too bothered about it.
I think Dahmage believes there’s a continuity error between the two films.
I’d recommend he rewatch the opening of Star Wars.
