This review is for those who did not read the books, and is free from worrying about the adaptation. I took my teenage friend's daughter who is a fan of the series to see this. I watched the movie with an open mind and actually found it somewhat interesting. The movie is flawed with more than a little melodrama and some bad dialogue, mostly at the beginning. But if you can let that slide, as well as a somewhat cheesy and unsophisticatedly presented romance, some entertainment can be taken from this movie.
To summarize, I say go if you may, but leave most of your judgment at the door, and you'll be mildly amused.
