I honestly had high expectations for this episode and obviously wanted to like it more than anything that came before, but... 6/10
1. I liked the planet, both aesthetically and the idea. Although it was just the Pandora from the Avatar. Yes, I acknowledge that they wanted to do something classically Star Trek, but it didn't materialize. Not enough insight into the Panava. Very little in terms of the story, just some dragged out scenes. It's not enough for the episode to be good in theory, it needs to actually be good.
2. Best Klingon scenes on the show. Don't get too excited, it's still not good, but at least wasn't putting me to sleep.
3. The first minute(s) of the fighting action was dynamic and I thought "this can only get better"
4. Worst ending of any Star Trek episode. When the preview started, I was like - this can't be it, can it? Felt like I watched 5 minutes into an episode, was kinda into it, but then nothing happened, except for a cheap cliffhanger "hold on, it's going to happen in the next episode" ... okay... then just make a longer episode, or cut out the dragged out scenes, but make it an exciting episode to watch. Very disappointed by the ending.
The good thing is that it looks like they're trying to go in the right direction (exploring alien worlds, introducing sci fi ideas) but they're not doing a very good job at it. And the bad thing is that STD broke its arguable streak of every episode being better than the one before. I'm also worried that they're going to be tying all "exploration" episodes into the overall boring arc, limiting them to a very narrow story beat. If this planet was explored without any connection to the stupid Klingon arc, it might have been very good. The difficulty of establishing communication with the alien planet, understanding how they evolved, their culture, etc. could've all been fascinating to explore and instead.. it just wasn't. I would've given this a 7 if it had some kind of a resolution at the end. Again, just a terrible ending.
Overall, if the Magic episode was a stupid idea with a good execution, this was a good idea with a crappy execution. On the other hand this was still second best STD episode.
