I've seen Cider House Rules, Unfaithful and Wendigo, not because they starred Erik, but because they seemed like good movies. The fact that they featured the youngster from MITM was a mere coincidence.
I also feel that the movie Unfaithful is intended for a very different audience to that of MITM. With references and themes of a sexually explicit nature, I can't think of anything more diverse than MITM. Erik seems to have a way of reaching out to a broader group of people.
Justin and frankie on the otherhand, seem to star in movies that are targeted at peoplee in their same age group. I have to admit, that none of the movies to which Frankie and Justin have starred in have ever appealed to me.
