Anyone who knows Tarzan only from comic books and films (especially Disney) does not know Tarzan.

The writing is better than most series novels of today. Burroughs used a wider vocabulary, wrote in complex sentences, and gave the reader a feeling of time and place, things not often done in mass fiction of today.

Obviously some of the premises were far fetched...for instance, teaching himself to read and speak a language he never heard, having nothing to use as a guide, except a few pictures.
