I think what I see with Cruise is the astonishing pride he has for himself. I'm not sure if I've seen anyone with a more self-congratulatory spirit about them.
That said, we all run the risk of this by forgetting one other critical virtue that we sometimes forget while trying to maintain the others -- humility.
To the other readers saying, big deal, what is the difference between his religion and other religions: Your point is well taken, however, there seems to be one critical aspect missing.
Most religions point away from the self and look to something else in which to improve the self. Cruise and Scientology looks at the self as if it is the answer for all of the major questions of life.
“There is something which unites magic and applied science while separating both from the 'wisdom' of earlier ages. For the wise men of old the cardinal problem had been how to conform the soul to objective reality, and the solution had been knowledge, self-discipline, and virtue. For magic and applied science alike the problem is how to subdue reality to the wishes of men: the solution is a technique; and both, in the practice of this technique, are ready to do things hitherto regarded as disgusting and impious" -C.S. Lewis
