well of course they have more lines! ok, granted the twins don't have a resounding role to play (so far) n the books, but they were so hilarious! i loved them. and ginny. they had to give her more lines. i mean, come on. so far she's been completely ignored in all the movies, she had no personality of her own, and for the people who are fans only to the movie, she was simply rons little sister who got dragged down to that chamber in the second movie. if the directors and producers and whatnot kept her the same ginny without any lines, come HBP, people are gonna see harry kiss her and think, "What the heck? that was random. it's not like we ever got to know the girl" so, yeah, i thought it was great.
