MightyMagnus, welcome to the madness.

I see that you see what it is I'm trying to say, however we must remember that "Fallen" for me was the whole "emotional adolescent male ruled by his hormones" college deal. Hence why all the lines between Shia and Megan are pretty much, "Do you love me, how much do you love me, why don't you say you love me" and I think partially why alot of people see Megan in a negative, another scapegoat per say along with the writers to devert any attnetion or more so, blame to Bay about what others think is wrong with "Fallen". Even I was getting tired of her towards the end of the film....but that wasn't in no part her, but just her recycled lines.
Megan, for me, has the potential to be a good actress. In the first film I liked her, she did the whole Teen Hottie thing during the high school bits, and played a convincing "Everything has gone to hell" routine during the showdown in the first films finale. Because she wasn't bogged down with lines meant to cater too much around the "strained relationship" dynamic as it was in "Fallen", it worked better.
As for the new girl, I fear her lines will be bogged down with such nonsense or maybe even worse in terms of feeling a need to outshine Megan. I will say I am happy they didn't try to recast the character, I prefer a new character all together. However honestly; comparing this Calry character against Megan can't be helped. I've already spoken to a few people, and they already noted a loss of interest in "Moon" due to Megan's lack of presence.
As for her moxy as an actress, I've yet to really classify her. She's been playing nothing but catty highschool characters for a good duration of her career, but she has a film coming out with Mickey Rourke (SP?) as well as possibly playing the next Laura Croft. She also has shown interest in adapting the late great Michael Turners "Aspen" into a film, so she has drive. As far as Moon is concerned, her presence would have certainly helped, and I think moon will suffer from a lack of it.
