Hell has no fury like a sci-fi fan whose source material has been scorned.

And to be fair, I can completely understand that perspective, and maybe it is a cynical ploy by greedy studios and ambitious writers who want their own thing put on screen, but if you're among the millions who are either not familiar with or not invested in the source material (coughHalocough), you can take these shows for what they are.

Foundation is nowhere near as tight as the Expanse was, and it's undoubtedly just letting sufficiently advanced math be a byword for magic, but it's well enough performed and there are a few compelling ideas floating around, and the narrative threads are finally beginning to come together. As someone who is not an Asimov reader, I like it quite a bit but don't love it.
