i read Rendevouz and Rama II and thought they were pretty poor, to be honest. i'm fucking down with some Clarke but for all the hype even normies have given this series, i couldn't really get into it.
Guns of the South by Turtledove, i avoided for years because i thought it would be a similar cringy white-power wankfest like The Turner Diaries but goddamn it was so fucking good
Yeah, I think he is extremely overrated, tbh. Even the Odyssey series isn't really that great, apart from the super in-depth description side of things.
Started reading The Mars trilogy (well, reading the short stories first) by Kim Stanley Robinson and its like a complete opposite, in a good sense. Actual human characters and plot!
