Both Hardiwicke and Weitz have done a commendable job in condensing the books and bringing the story to life. Talking about TW, there are a bunch of stuffs that the movie has captured perfectly. To begin with, the weather of Forks was very well illustrated. The way Meyer goes on and on about Edward's out of the world beauty, glimmering eyes, mesmerizing voice, marble-like skin that sparkles in the sun, perfectly-built physique, frequent mutterings, painful resistance against Bella, etc in the book, it's almost impossible to concentrate those God knows how many unbelievable and cheesy qualities mentioned in the book into a human. Edward's characterization was excellent. I was hecka surprised the first time I watched TW coz Edward was exactly the way I had imagined and was totally up to par. Edward and Bella's unconditional and obsessive love for one another could be felt throughout the movie.
I thought TW did a good job portraying Bella as well, considering that she's described as a reserved, delicate, pale-skinned, clumsy, vulnerable girl who hates Forks, isn't very much comfy being the center of attraction and likes to remain unnoticed by people.
Irrespective of the gender of the two directors, TW was the first attempt to bring the characters in the book to life. I wouldn't say it was perfect. There were some parts where it required more polishing. So, obviously the director of NM should've been able to take those flaws into account and work on making the second attempt even better and he actually did for the most part. What TW couldn't capture well enough was actually captured by NM perfectly. The general wardrobe, make-up and visual effects were better in NM. Needless to mention Jacob's portrayal in the movie. I thought NM was a complete somersault for Jacob. I would anyday prefer the wolfboy in NM to the Jacob that hardly had much footage in TW. But then, he almost replaces Edward in Bella's life in NM. So, it's a given that Jacob has the lead role in this particular movie even though the main character is still Edward on the whole.
Agreed that NM is supposed to be the darkest phase in Bella-Edward's relationship and Jacob was like a filler in Bella's life when Edward was gone for a while. But that doesn't mean they should've tossed Edward aside in the movie. NM couldn't preserve Edward's character. The least they could've done was to carry the tradition and keep the character unchanged if they couldn't make it any better. To me, Edward in NM was a huge disappointment. Just take Edward's belly hair for example. Jesus! His skin is supposed to be all that plain, marble like and smooth, rite? And what was up with his gloomy and high on crack kind of expression throughout the movie? NM's depiction of Edward totally sent all of those heavily embellished, out of the world, cheesy descriptions down the pipe.
The two movies speak for themselves when it comes to explaining how male and female modes differ. The series was written by Stephanie Meyer, a female. So, that might be one of the reasons why a female was able to do more justice with Edward's character that is supposed to appeal the female mass. It's apparent that the female director of TW is more inclined to bring forward the deep seated and emotional aspects of the book unlike the male director of NM who is more into visual and masculine aspects of the book. Not saying that Weitz failed to depict the lovey-dovey stuffs between Edward and Bella in NM but Hardwicke was just a lot better in that department. Weitz did a good job with human to werewolf transformation, Edward's reflections, the mopey tone of the movie, and above all, Jacob. Jacob is such a piece of eye-candy in the movie. "droooools"....Also, I felt that Jacob-Bella relationship was a lot less cheesy and a lot more pragmatic than Edward-Bella relationship. Perhaps that is also coz the movie was in a male's hand this time.
