Mr. Anderson made a universe for himself and now goes around exploring it.
Why not?
There's plenty of genre-hopping directors who suck it (go see Sunshine for a good example of another Danny Boyle total piece of shit, or follow the degradation of Nicholas Roeg (everything post Bad Timing)).
I don't mind giving Mr. Anderson a few hours of my life every few years for another slice of a universe that part of me wouldn't mind living in.
Although I would like for him to do a sci-fi/spy movie and a monster movie.
