[spoiler] End was not good (little bit)
[SPOILER ALERT]
I think, it was not good and un-natural that
Liza killed Addison in the end.
No sister kills her brother just like that, specially when they had strong bond.
It would/could be more good if Addison was killed by Police,
because he also killed lot of police officers in the movie,
so being encountered by police could be more fairer.
the end scene could be like:
when Addison asks Jay "Do you love her?"
He says, Yes.
There, some desparate expression should be shown on Addison's face,
he would stand up, and throw the gun in the feet of Jay,
just right there, police (as already arrived) would shot him from behind and killed him.
that would be much better scene.
Also.
It seemed,
"Addison only killed either bad-guys or police men."
it could be more nice, if film makers made this statement more true.
because they also showed that he has some sympathy, as he saved woman and her children.
But the only one scene when he killed a man to snatch his ice-bike.. ruins this idea .. for Addison/Eric.
