I think one aspect of silent protagonists that people tend to overlook is that you can do some pretty interesting stuff with them that you couldn't do with a protagonist that talks. I think my favorite example of this is Jacket from Hotline Miami. Completely silent, and not because the game is shy about dialog, but as an intentional choice to make Jacket seem like a very distant, detached character. You see him do actions that make him more human (like rescuing the girl and aiding her in his apartment), and during the Mask talk scenes, the dialog can be interpreted as being told to both Jacket AND the player, which is very interesting.
TLDR; You *can* make interesting silent protagonists, you just need to know how to characterize them well!

Hotline Miami is an interesting game, as the character makes the decisions to be bloodthirsty (and the game's checkpoints feed into this lack of control). Additionally, the plot twists need to convey a number of meanings simultaneously.
Perhaps a voiced protagonist could work; but it's extremely difficult. Content writing is a difficult artform.
