Wild west planet is a must but ethics was really out of left field and was hilarious too. Funny enough it was the movie references that really surprised me I would never have thought of Spock's sacrifice or the space dock escapeIt's probably recency bias, but this feels like my favourite episode of the series so far.
The training simulations were a great way to do call backs, and I love that they used a mix of bigger and smaller episodes (if you had given me the basic plot of this episode and told me to brainstorm, I think it's fair to say that "Ethics" and "Spectre of the Gun" would not have been on my list). Shari Yn Yem's nefarious motives was a great twist on similar characters.
The moral of the story was heavy-handed but effective and I'm curious to see how it bleeds into the rest of the season.
