I’m with you on Redshirts in So Many Ways, but there are some bangers in the past 20. Spin was good, Rainbows End was really good, I know the Yiddish Policeman’s Union was highly lauded, I loved The City & The City, Ancillary Justice was fantastic in all the ways Sci-fi should be, The Three Body Problem was really good, I know that Jemesin was loved, The Calculating Stars was excellent, I’m currently working through A Memory Called Empire (but Gideon The Ninth was AMAZEBALLS), Network Effect was fun - but I love Murderbot. For 2022 I loved Master of Djinn (that’s some great worldbuilding there) and for 2023 The Spare Man was the “Thin Man in space” I didn’t know I needed (but am totally the target audience for).
