he definitely made the right choice with not showing the video. there's no possible scenario or a situation, where a video of a man who dedicated a large part of his life to grizzly bear ended up getting eaten by one isn't inherently hilarious. herzog pretty much conquers the impossible by task by somehow making the film vacant of any of that seriously huge comedy premise.
also, you do realise the girlfriend got killed too? or am i horrifically missing the point
edit: i've been laughing for the past 3 minutes at the thought of watching the video
