The reason most people see Vin Diesal as a shitty actor is his failure to absorb & become a role. When he plays a part, you don't see the part, you only see the Diesal and his catch phrase.

However, this may be right up his alley, similar to playing, say Ghengis Khan... he doesn't need much skill as an actor. Hollywood & the masters of Special effects will fill the film with enough eye candy, we likley wont focus much on a poor front man.
