i quite agree with u but one thing. and the thing i object to u is in all the reviews of the movie. u say - don't get to know enough about POrtman's character, Sam. i wonder how u can say that. unless u r referring to her profession, which might/ might not be mentioned. but everything u need to know about her is out there in the film. why she is so chilled out, why she can crack those kind of jokes. why she dances and makes herself look like an idiot. etc. everything about her is all there. yes, while it is not told out, it is all there tho.
