I think it really depends on what you're looking for when you read SF.
For me, I usually don't care very much about the characters or excellent prose or a lot of the typical 'literary' qualities of a work. When I go to SF I typically am looking for exploration of interesting ideas, settings, or premises. So I find myself being more forgiving of 'bad fiction' if it's the only place where I can find a particular idea being explored.
The way I see it, "someone who writes stories deferring to actual scientists for review" tends to end up treating science as something to throw onto a story to give it a veneer of legitimacy -- like various fantasy/space-opera shows that have 'science advisers' to supply the technobabble needed to make it sound plausible. Interstellar was probably the best example of this going right that I can think of, with the feedback from scientists playing a big part in how things were portrayed and explored.
In general, though, I think that what makes a lot of good SF interesting is the focus on ideas that may only come from having a writer who obsesses so much about such ideas anyway. It's why I'm frustrated by a lot of recent popular SF TV/movie series that tend to gravitate into the typical "character-driven serial drama" format that everything becomes.
