As a degreed engineer and employed in a technical field, I have done/do plenty of reading for learning/work stuff, and even plenty for my hobbies. But usually when I want to just relax I just want to get lost in a good fiction book. SF is my usual choice, and while there are plenty of poorly written books out there that just make me face palm at the absurdity of the 'science' there are ALSO plenty that, while I may intellectually know that what is described is impossible based on our current understanding of physics, it's not so blatantly obvious because the author didn't use some silly pseudo-science to justify it all. And I don;t find it hard to overlook such things. I also like action/adventure and fantasy, and you have good and bad there as well. A good author has well-defined characters and if they are going to have superhuman powers, there still are rational limits. Otherwise you end up with tripe like the Twilight series where the supernatural powers are whatever the author needed to get the character out of a specific situation. That kind of BS is just unreadable. Sometimes an author has so many of the details correct, that when I hit something where they just get it totally wrong I literally cringe. Something that stands out to me because of my interests - a lot of times these types of things revolve around transportation. The author will have every detail of the characters weapons correct. Every detail of the streets in the city they are in correct (and it's not, according to the author's bio, where they live - so they HAD to do some research), and then they make up some BS car for the character to drive. Happens in movies all the time - one of the ones that really hit me that I IMMEDIATELY saw is in the movie Ray, about Ray Charles. A scene from the 1950's, Ray and his band are driving to a gig. In a period proper car. With other period proper cars on the side of the street and also driving along. They drive under a railroad bridge - and a modern double stack container train passes overhead. I guess the director figured no one would ever notice so there was no reason to reshoot the sequence. And I suppose he was right, because while I saw it immediately, I was watching it with my ex father in law, who worked his entire life for the railroad (as did his father before him) and didn't see it until I backed up and replayed the scene. It wasn't way off in the background, it's like the top 1/3 of the frame.
Anyway, despite my science and technical education, I do retain the ability to suspend disbelief and enter a fantasy world where things like warp drive exist and actually enjoy it, rather than pick it apart for breaking all known laws of physics. To be honest, I sometimes pity those who can't escape the real world, ever so briefly. I think it keeps me sane.
