I don't see him caught in that rut. I think he has enough going for him where the sfx is part of the story, not the whole story, as is the case in many a .cgi infested "blockbuster" today. I liked his cinematography, the way he places his cameras, the performances he gets out of his actors and his way of telling a story without having to explain it all to the audience over and over.
The bottom line is that I look forward to seeing what he comes up with next. I am the same way when I go to see a film by a particular director that I like. I go to see what he/she has come up with this time.
