I watched THE NEW ADVENTURES OF TARZAN havin no idea that it was the condensed version of a long-length serial, which explains the confused, disjointed nature of the running time. Much of the material comes from the first episode of said serial, and it's a lively enough story, with Tarzan on a rescue mission and lots of wildlife interaction to add colour and excitement. It does get rushed at the climax though, and as someone who avoids abridged editions at all cost, I recommend skipping this in favour of the whole thing.
