All of your points are actually mentioned a lot by people who've watched it, and they are all valid. I completely understand what you're getting at.
The Klingons are very different, everybody noticed that, and as far as I know there is no in-universe reason for it. What I did like about the Klingons in Discovery is that they were fleshed out more than I'd seen regarding their houses and social structure, and the show addresses some very interesting themes (most notably xenophobia) which are affecting life today, something that Star Trek has been known to do continually through the years. It doesn't do it in its regular way, especially because Starfleet - our good guys - is not necessarily the only victim, but it does it. Some people like it and some people don't, and they are both entitled to their opinion.
Also, the feeling in itself is much darker than we're used to. Like I said, Starfleet is not necessarily the good guys anymore simply because they say so. (I'm not giving away any spoilers, as you've probably already noticed some aspects of what I am referring to). It was a twist of storytelling I particularly did like.
And as for the futuristic stuff, yeah, I also frowned a lot (especially in the third episode) because I was wondering if they should have been able to do certain things at that specific time. I mean, I understand why it looks much more futuristic than TOS or "The Cage", because really I wouldn't want to see the same kind of sets and costumes and hairdos from the 60s so I get to feel like they really are linked together. No. So I get the look. But the content seemed to me to be a bit advanced, yes, but I eventually learned to get over it and just enjoy the show.
But overall I really did enjoy it a lot. I was really surprised about how deep into their characters they went, and I was glad. In my opinion, that was the best aspect of the show, their characters and their relationships and growth and how deep they went into their emotions. I also like the story arc, it did have me wondering what was going to happen next and hate having to wait a week to find out.
I hope that gives you some insight as to one person's opinions on the show, and I hope you continue to enjoy it. If you don't, then like I said, you're entitled to that, but I do think you should finish watching it. Good luck
