I've just freshly finished reading the entire Foundation series in anticipation of this series, and so far I'm pretty disappointed with the first episode. As it started, I was wondering if it was the same book...
In the books Gaal Dornick, apart from being a man, is already freshly qualified as a full Doctor. The actress here looks like she is only in her teens. The very first scene about the Vault with the kids trying to approach, I don't recall in any of the books. I seem to recall the whole lead up to the meeting of Dr Seldon very differently, with Gaal first visiting the top of the metal dome. The dome and the weather management does not seem to have featured yet.
So yes it appears so far to be a loose adaptation, and I'll have to see if I get to love it... But I can really recommend reading the books which obviously are able to give a lot more background detail, and to me, seem to have more to the point dialogue and even a faster pace...
See Apple’s Foundation starts out big, lavish, and a little boring
A slow start for the sci-fi epic.
