[Q]: I agree, this is a great intro to Tai Chi Push Hands . I've always wondered what Push Hands was - this video explains that in great detail and teaches how to learn in a very gradual manner. I got my copy last week (...)    Im glad I finally found this DVD, because it shows exactly what I was looking for - I once saw two women 'pushing hands' in the park and was fascinated, but have never found a video on the subject until now. Nice sound and picture, and Dr Yang seems to be a very nice teacher
[A]: POS


[Q]: a telling picture of the future . This movie came out the same year that the Supreme Court gave us abortion on demand via Roe v. Wade.  How ironic is that?  We are living in these days to a certain degree already.  This film is disturbing on many levels because of it's impending reality.  I highly recommend it as a wake up call.

[Q]: Superb . Just in case the preceeding reviews don't settle the question, I'll add my unqualified rave to the list.      The subject matter of this film is important for many reasons and is equally full of dramatic potential - this movie makes the most of both.  The screenplay is constructed like a Beethoven symphony - logical, constantly moving forward, boiling with energy.  The script, presumably, is based on the original transcript of the conference.  The acting - well - how can one praise it enough?  The human drama - the constant interplay of personal politics, intellectual fencing, bestial attitudes and genuine emotional reactions to the subject matter being discussed - it's captivating from first to last.  And the last scenes are superbly poignant - the final intimate focus on both Heydrich and Eichmann as shallow men and profound monsters, the use of Schubert (as both reference and musical score) to underline the moral desolation and irony at hand, the final roll call to enumerate the sober injustice of the participants' ultimate fate.    This is yet another HBO movie which raises the bar for American cinema, proving that one can still make a great statment on film without either large budgets or avant garde methods.  I can watch this over and over and always get something new out of the experience - which, of course, is the very best recommendation for actually purchasing a movie on DVD.  Buy it and watch it often
