I haven't seen it yet. Looks interesting! Rav Soloveichik was a master in psychological insight, textual analysis and an incredible pedagogue as he induced all who listened to engage in some soul searching. His Teshuva lectures as recorded in Al Hateshuva are a masterpeice, and ever since my first year at yeshiva, his ideas have been an ongoing presence in my consiousness of the Yamim Noaraim.
I do wonder, however, who put the Machzor together. (Elul is certainly NOT a time to air the dirty linen of all the different parties who claim the Rav as their own, viewing Rav Soloveitchik in their own image. Suffice to say that there is a great range in the manner that the Rav is remembered, and that no one is objective here.)
