It depends what the author promises. If I read a hard sci-fi novel, and the author makes a basic physics mistake I will not take it kindly. But if the premise is wild I am happy to roll with it. I think the best, most enjoyable SciFi asks you to suspend your disbelief with regards to one fact and then rigorously explores the consequences. Here is a mini review of some stereotypical examples:
Katya's world presents itself as a hard SciFi on a water planet where the whole action is happening on submarines. Deep in the water is a layer where some very heavy mineral is suspended in the water making it even a lot more heavier than water already is. Inevitably the protagonists submarine sinks into to this 'soup' as we approach the great showdown -- absolutely sucks. How can it do this? A submarine is more or less neutrally buoyant in water. It cannot sink into a liquid that is much heavier than water, it would just bob on top of it like a balloon. Ruined the otherwise good book for me.
Gideon the ninth -- the tagline for this one is "Lesbian necromancers in space," and that's what you get (though the lesbian bit is very much between the lines). A wild story where whole planets get murdered and cruise through space as zombies (not their population, the planet itself). No issues with this -- big fan.
Project Hail Mary makes one assumption: A unicellular lifeform that is very much like plankton has evolved a way to interact with neutrinos (particles that interact with almost nothing). That's it. The rest is rock solid science, and the learning about the consequences and the way they are studied is fascinating. Real physics problems and their solutions add so much surprise to the plot.
In conquest born is grimdark social fiction, set for convenience in a SciFi world. Here the point is to explore how society can work and technology takes a backseat. The author stays honest and never abuses technology as a miracle solution for plot problems -- excellently done.
The Rig. This one seems to be very popular with reviewers recently. Now if I open a book titled 'the Rig' I expect that the action takes place on a rig of some sort and that science and technology play a big role. The book has some nice writing, but the author displays a disdain for science and the plot is so thin that it can slip through the gaps between atoms (moreover the rig is noticably absent for most of the book and when it shows up, it has the vibes of next-gen startrek, rather than a grimy drilling platform). The author probably thinks of this as social fiction, but it doesn't live up to this as consequences of social constructs are never explored beyond the blatantly obvious -- sucks.
