The thing I always found weird about Titanic was the end sequence where Rose is reunited with Jack (in heaven??). What about her husband? Her children? She knew Jack for what, two days? Man, that end sequence still bugs me. It's like, yeah, he encouraged her to go out and live this great life, but ultimately nothing she did after he died mattered as much as him, so clearly she would want to spend eternity with him on the phantom Titanic. (On the other hand it is a movie, and the scene works as far as giving emotional closure, since we never meet her husband or family other than the granddaughter, and thus the audience has no attachment to them.)

I agree that the majority of women's roles in TV and movies are sadly underwritten. Most romcoms are very annoying because the main aspect of the woman's identity is that she needs a man in some way. There are a couple 80s romcoms that I really like, Working Girl and Moonstruck, where the movies are really the woman's story and the romance plot is just a part of that. I can't think of any really recent movies that fit that mold, though.
