Yes, I watch it each time, with renewed enjoyment. I know some people think the Berlin scenes are slow, but I like the paranoia that infuses them, and Pleasance makes a great Himmler, a bit creepy and weird but dangerous as a snake.
The bit IMO that lets the film down is that last battlescene where the US troops take down the Fallschirmjager; it always looks rather fake and half-hearted.
