I don't think watching this will harm anyone that much mentally, although there are some things to consider. First off, I have to admit, I've seen the first 3 films and I have read the complete series, I read the books first and started really turning my opinions of this series when the movie came out. The acting is really bad in this film, I really do think it is mainly the lead, Kristen Stewart's acting that makes this film completely uncomfortable to watch, but that's a personal opinion on someone's acting skills. The script for this movie wasn't well done, in most movies they create from books, they have to cut stuff out, in this film however they could have made some stuff up, probably would have helped the movie. It isn't that interesting until you get to the end when there actually is the only bit of violence and action in the film, the rest is quite boring besides when she almost gets hit by a van, that's a little interesting. Most people could probably watch this movie and have an opinion that it was neither good nor bad if they didn't deal with the hype this movie created and they hadn't read the books originally, but because I did both, this movie was such a let down. Although one good thing about the movie, it helped young me see how twisted this book was. It is inappropriate no matter who you are, to sneak into someone's house to watch them sleep, however this happens in the movie and the book, it's creepy. Not only that, but they used this very creepy, stalker-like move and pegged it off as being romantic, which it isn't and no one should be taught it was. Also, and this is digging past the storyline and into the characters, the fact that this series has created a female lead character that is not only so helpless, but can be quite stupid at times as well, is just boring on sexism. The worst part, this was written by a woman who is being sexist towards women by saying you either need to be another species (Ie Werewolf/ Vampire) or a man to be powerful because who helps her? Men and supernatural creatures, yeah, the implications in this film are not good if you look at it through a feminist perspective. But that also means it is being sexist towards men as well because they have to be strong and powerful, they can't receive help individually. Although that being said, this film will not likely mess up your small child, all I know is you couldn't pay me to watch that film again.
