I seriously need to re-watch *all* of Herzog's films, but in the flicker of memory this is my favorite.
For me, the static camera-work fits the hothouse atmosphere of Buchner's play perfectly. I think especially of the early scene where Woyzeck is shaving the Captain, and the camera doesn't move *at all* for what seems like forever ... technically, it is reminiscent of some of Jim Jarmusch's early films where the camera is hilariously static. Here, it is horrifyingly static.
And Kinski has never been more possessed, more demonically almost out of control. I just can't watch him, particularly during the intense (slow motion!) climactic sequence, and then "come back" to Hollywood movies and watch ... well, say, Kevin Costner. Sorry. Guess I'm a snob.
Finally, the strange, sawing music just sends me over the top every time, my skin tingling. To me this is an absolutely unforgettable, brilliant film experience. It disturbs the living hell out of me, and I like that.
