I watched his film Bitter Lake and mostly thought it was a waste of time. The information content was trite, slow, and where he was trying to make an argument it was single-sourced or poorly argued.

Again, the primary feeling was not that it was wrong, or whatever, it was just that I could have been using those two hours to do literally anything else and it would have been of greater value.

Whether any of his other films are better, I don't know.
