As far as I can tell, I can't get from a movie shown under "so-and-so also rated" on the left to the mute button. Mute doesn't appear when hovering over the movie, and clicking on the movie opens a panel on the right which doesn't have the mute button either. And the same goes for movies I search for; searching opens the same panel on the right, which still doesn't have the mute button.
Well, since muting is not yet taken into account in the algorithm, there's no point in muting a movie you and someone have in common, or a movie that you would directly make a search for.
