Well, it is led by a man who pretends he is a monsignor, which means he is both worldly and ambitious.
Not a great mix for a founder of a religious order.
Additionally, they seem to be more concerned with living a Baroque lifestyle than priestly vocations.
Finally, they are not principled, doctrinal traditionalists (i.e., they will have no issue with saying the Novus Ordo from time to time, and adhere to the tired line that there are no heresies in Vatican II docs, just bad interpretations).
Lots of focus on accidentals.
I was a postulant there for a year.
