Those who are critical of Asimov's Foundation series should remember that when it was written the field was rather young. Also that Asimov was rather young. Those who find it perhaps cliche-ridden should recognize it as the source of some of the cliches.
Another early "cliche ridden" title is "A Princess of Mars" by Edgar Rice Burroughs.
When I first read it, initially I thought it was a ripoff of generic sci-fi, fantasy, superhero, etc ... in an easy to read book. But when I noticed the original book publication date was 1917, I came to the realization "Princess of Mars" may very well have been one of the early original sources of sci-fi/fantasy/superhero tropes.
