This rather silly follow-up to Cat People isn't so much unwatchable as it is merely unnecessary.
If you watched the documentary on Lewton in the box set that you reference, you would know that it was not meant to be a "follow up". It is successful as a stand alone movie, and is an interesting reflection on the imagination and private world of early childhood. I didn't find it silly or unwatchable.
