So I listened to it again to see if I could clarify what he said about the Ralbag. It’s pretty hard to make out what he’s saying. After he says that Moreh Nevuchim is good he says “but the _____’s seforim _____ the Ralbag is not so good”. The first blank sounded like he was saying Rasag, Rashag, Rashal, or Ralbag. Presumably he was referring to R’ Saadia Gaon or the Ralbag. If the first blank was “Ralbag” then it seems that he was talking about all his seforim, not just Milchamos Hashem. If the first blank was something else, then he might have only been referring to Milchamos Hashem when he mentioned the Ralbag. The second blank might have been “like” or “but”, which I’m not sure how would fit in the sentence, or it might have been something else entirely – it’s hard to distinguish.
And I also noticed that he also said that Nefesh Hachaim and Kuzari are good as well.
