The latter three yes the first two not so much which is a shame really, just imagine if the Klingons had spoken English from the start with Klingon subtitles and had used recognisable updated D7's and Birds of Prey at the battle of the binary stars.
There were vitriolic "fans" that would have hated the show no matter what (not speaking of here really, more other forums, youtube commenters, reddit, etc.) that then would have complained that the show should have had more Klingon in subtitles. And none of that Sans-Serif crap, be original whydoncha. I don't think there was any way the show could have swayed the true haters.
but yeah, I wish they'd done English from the get-go. The Klingonese stuff has been the shows weak point repeatedly.
