Perhaps I am just good at facial recognition, but....SPOILERS
I never had a problem with telling the difference between Tori and Heather. I wish I hadn't deleted it from my DVR, as I have actually forgotten most of the film (I guess it didn't make too much of an impression, though better than "Not Cool"). I would like to watch it again to see why people are having such a problem with the two. Again, perhaps I am just better at facial recognition than a lot of people. Having said that, if it is a problem for a lot of people, it's DEFINITELY a problem for the film, as it's not like she could just go back and reshoot it with a different actress in one of the roles.
I see a bright future for her in films, and this is something she can learn from, for sure. There's a lot she needs to learn, but her future seems more promising in film, at least to me, than Shane's.
The plural of mouse is mice. The plural of goose is geese. Why is the plural of moose not meese?
