Do u think alec and jane should have acted closer in the movie (i duu)

Yeah, definitely. And they should have acted lebih too! Two awesome characters, but they merely made Jane take Alice, Bella and Edward to the volturi towers, and aro practically didn't do anything at all but hug Jane when she got back and praise her.

Definitely, Alec and Jane are known for having a very close relationship. They're twins after all and I think they share an impossible pain due to their last human day. (Burned at the stake) And I think that's why they enjoy torturing humans that much, because they want them to pay for what they did to them. I mean, how could two innocent children ever be that sadistic and bitter? But that's just my theory. I definitely think they are WAY closer then they showed in the movie.

Yes,I think they should acted lebih close in the movie and to appear much more.

I think they should have. In the movie anda wouldn't even think of them as twins if Alec hadn't berkata "sister" to her. And Aro didn't even interact with them as much as he did in the book. In the movie it looks like he doesn't even care about them.
Maybe it will be better in Breaking Dawn. atau not, we will see.

yes for sure,after all they r twins and have a strong bond and r most populer in the buku why can't they be in the movies?

of course!!!
i had no idea they were even related until somebody berkata something about them being brother and sister
i mean, do they even talk to each other at all?
i know they dont in breaking dawn but i dont remember new moon
so....yeah
