Three early Asimov novels

I just finished three old novels by Isaac Asimov - The Stars, Like Dust, The Currents of Space, and Pebble in the Sky.

TSLD is a book I remember my dad telling to read once. He knew I read a lot of science fantasy, and he recommended it as "the kind of books I read when I was your age". I had tried to read it back then, but it didn't interest me. The basic plot is a 'someone is trying to kill me' mystery that spans a few solar systems. It's pretty interesting, and I wish I could have talked about it with my dad.

TCOS is a sort of pre-cursor to the Bourne novels. By which I mean the main character cannot remember a thing about his life, and throughout the novel he slowly recalls various facts. A larger and grander plot is revealed throughout, leading to the ultimate showdown between all the characters.

PitS has a leading character zoomed forward thousands of years into the future. He is given a treatment to make him super-smart and thus he learns the language and gains telepathic abilities. There is a huge plot for the Earth, delegated as a second-class planet and widely disdained by the other millions of worlds, to destroy all the humans on all the other worlds.

All three are a little confusing. It may be because I always read them late at night, but I kept getting all the characters confused. Also, all three seem to magically wrap themselves up in the second-or-third-to-last chapter. I'm sure they were all pretty groundbreaking in their day, but now they seem a little trite.

Don't get me wrong, they're all fine books, but they all seem a little... dated. Which makes sense since they are all 50-60 years old. I should be so lucky to write anything that holds up a tenth as long.
