Yes, if you are looking for the usual brilliant Welles camera work, "Around the World" will leave you cold. They are very "slapped together"/"quick, put the camera here and let's shoot this!" school of production. But I don't feel this harms the material (that much).
In "One Man Band", Oja talks about Orson's "F for Fake" as a "visual essay" (I think that's the term she used) and these are exactly that. Take them as light, breezy conversations with Welles on subjects he found interesting.
As well as the episode I mentioned previously ("St. Germain Des Pres"), other highlights include Welles interviewing a group of utterly charming old widows & retired soldiers in "Chelsea Pensioners" and exploring the small world of the Basques (whom I'd never heard of before) in "Pays Basque Pt I & II".
I think only the Bullfight segment with Kenneth Tynan & his wife suffers in comparision, because for some reason Welles choose to have them narrate (stutter & all) instead of himself for the majority of the segment.
Anyway, take a look at these again, they really are quite wonderful.
