I would say in general, I prefer established characters over blank slates, but its not a deal breaker by any means. How I feel about it really depends on how heavy the game goes with sim/avatar type features...if I'm expected to really live through the character than I'd prefer the character doesn't have a voice that sounds too foreign, or it ruins my immersion. But if there aren't avatar features or the story is mostly linear, than a silent character can potentially hurt the overall experience, especially when everyone else around him is fleshed out and communicating normally.
That being said, overall I wouldn't say it hurts or helps the experience, just really depends what the game is going for. Tales of Xillia 2 is a great example of a well characterized silent avatar for example, for a character that doesn't talk he gets more character development than many established MCs.
