Do you think the twilight series could have been written better?

It could have been better if:
-There had been a plot.
-Vampires weren't perfect.
-Boys weren't falling at Bella's feet left and right.
--Or if they were, if Bella was actually nice, thus giving them a reason to do so.
-If the characters had had individual personalities, rather than just stereotypes.
-If Bella had had more of a backbone and didn't whine about EVERY. LITTLE. THING.
-If there was a reason for their romance.
-If Edward wasn't a stalker.
-If side characters (ie Esme, Jessica, Lauren, Angela, Billy, Tyler, et cetera) had been given more in-depth personalities than just 's/he loves Bella' or 's/he hates Bella.

The list could go on for a long time, but I'll stop there.

Yes, the Volturi should have had a collection of vampire heads belonging to all the vampires they have killed, just to proove that they are intimidating.
It would have been great if Edward kept Victoria's head somewhere.
I think Emmett should have came onto Bella a few times. It would have added some interesting tension within the family.
Inspired by one of the picks recently asked here, one of the shapeshifters should have imprinted on his own child.

That's actually all I can think of right now.

God yes, it would appeal to more people if it were written better than it was written.
And if there was a fight at the 'climax' of breaking dawn.

I feel like the Twilight books were a bit rushed and could have used more planning. Especially strengthening the plot and giving the characters (specifically Bella) more traits. To be honest, with a couple plot twists (ending to Breaking Dawn mostly) and better writing, Twilight could easily be a very successful franchise for both both and girls and all ages to enjoy :)

Absoultely 100% yes! here are some things that would make it a vampire series:

1] Bella should be more independent and strong than she was unfortunately made to be. Instead of being in the backround and acting like the damsel in distress, Edward should have let her fight along with him, and give her some bad-ass fighting skills! plus have her not act so gloomy and selfish and care more about others than just Edward all the time.

2] Don't have the main romance of Bella and Edward be the focus of the series. Maybe have other characters have love interests too.

3] Let Bella's human friends be a part of the whole vampire thing too. It would show that humans , vampires and wolfs can put aside their differences and come together. In fact, there should be a part in the series where the vampires try to take over the town or something and have EVERYONE in Bella's circle come together and defeat them, like the Battle of Hogwarts! that would have been awesome!

4] Bella should make something of herself after high school and later get married and have kids.

5] finally, NO SHIRTLESS MEN!!!! it's completely pointless!

Yes of course! There are so many problems about the book Twilight. Firstly, it has a little too much love and romance and no action! It needs to have more characters and the plot is annoying. The plot should be something like Bella who is the one who doesn't like Vampires, but she isn't scared of them! NOT AT ALL. Well... stupid!

Amongst numerous other things that have already been mentioned, I think that Twilight would be much more believable if Bella had acted a little more surprised, scared, and even a little sceptical when she found out that Edward is a vampire, rather than "Oh, you're a vampire. Cool. I know I should be scared but it's okay because I love you because you're hot and you smell nice".

I also think that Edward could lose control and maybe attack Bella or something- their romance is way too perfect.

If Edward didnt sparkle

In a technical sense, I wish there was a limited use of adjectives because I have never yet met a seventeen year old girl who uses scintillating or incandescent to describe their boyfriend.

I also think there should have been must more tension and much higher stakes. Bella should have been close to her mortal friends and family to make her choice much harder. There should have been a threat to Renee or Charlie - Charlie should have died at the end of Breaking Dawn. A Cullen should have been killed or lost a limb in the final battle - which should have been a battle.

Bella could have had a better character development in the story. Like,in the beginning of the series instead of her just agreeing to date Edward she should have decided fully and it should have been harder for her to decide. I also think Meyers should have made Bella's character to be less of what she made her now and into a stronger character who isn't a side-character and a damsel in distrees. As for Edward,I didn't like how so made him so perfect. He should have some faults in him and the fact that he sparkles is a little weird. She should have also made Bella be a bit more closer to her friends at the very least. I also think she and Edward could have gotten together in the last book instead of the first. It would add to the feelings that would grow starting from the first book to the last.

Generally no. I think it's a hugely successful series for a reason ie everything works really well together as it is. There are a couple of things however that I personally could have done without. I wasn't too big a fan of the sparkling thing (I personally don't find a sparkling hero to be sexy) and I didn't like the “total need to do anything to please and protect the other person” aspect of imprinting. That to me was too similar to the house elves compulsion and need to serve wizards – something that I found quite repulsive in the HP series.
