Tarzan Of The Apes (1918) struck me more as interesting for its position as one of the earliest movies ever made than for its aesthetic values. Part of the problem may be the fragmentary nature of the print we viewed (hosted on Amazon Prime), but from what we could tell, it was virtually plot-free, Tarzan seemed to be fat in a way that would not make sense for a kid raised by apes in a jungle, and he found it necessary to (silently) thump his chest and yell after winning several fights, including one with a mangy old lion (we felt sad for the lion, but that comes with its own collection of questionable moral thoughts). Throw in a bit of racism and a dubious leading lady, and it was all, actually, quite the bloody bore.
Tarzan never really did anything for me, truth to tell.
