It is, and I'm enjoying it so far even though I'm only a short way in. :D The only thing is that I'm wondering if I should go back and re-read the censored one first, since it's been years; I'm thinking I might see whether to read it after. The one I'm reading is the version that was put back together by N John McArthur - apparently two guys simultaneously decided that the original version should be released to the public - I'm told the Frankel book is much more academic whereas this one's aimed at lay readers.
