I recently watched Star Trek: Discovery Season 1, on Blu-ray. Excellent show! I was extremely impressed by the storyline, effects, acting, and cast. Well-done! Some observations:
-Great opening theme credits & song; it had a retro late 1960's vibe/tone, which was obviously an intentional homage to the Classic Trek series (or, TOS for short).
-The effects were the best I've ever seen for a ST TV series - especially the exterior space scenes with the various colors, etc. - nice.
-It's interesting that in ST: Discovery they depict the Klingons as completely alien, sinister looking, & almost animalistic; I don't think they've been depicted this way in any other TV/film ST series. I'm glad the Blu-ray set had subtitles re: their language.
-Interesting that Sarek (Spock's father) played a critical role in this series, as the mentor to Michael Burnham, who had her parents killed when she was a child, and was taken under the wing of Sarek & his wife.
-The "alternate universe" sequence that was a critical plot point in the last 4-5 episodes was extremely interesting & complex. You really had to pay attention to follow what was going on here. This was obviously a homage to the excellent 'Mirror Mirror' TOS episode.
In closing, though the show was great, I also found it somewhat complicated. I will probably need to watch S01 again in it's entirety at some point in the next year. I always benefit from a second viewing of shows like this, so I can catch what I may have missed the first time around.
Side-note: I know S02 is now airing, but I will probably just wait to watch the entire S02 on Blu-ray as well, so I can watch all of the episodes back-to-back. I suspect this will be released towards the end of 2019 (S01 came out on Blu in November 2018).
