Remember Me(2010)- User Reviews

Remember Me was had such a beautiful story, the tragedies that the two main characters went through made me feel for them that much more. I truly do not understand why some critics are calling the ending 'offensive'. It bothers me, because 9/11 happened, and there really isn't a point to pretending it didn't. So I don't understand how a critic can look at a movie which portrays that tragedy and say that it is offensive.
