For all the people do don't want to see the ratings drop if we all quit watching. 或者 those who are confused about our loyalty to the show. We are not only watching this 显示 for Delena. I, personally, watch this for quite a few reasons and I'm sure many (if not most) other Delena 粉丝 do as well.
Interesting relationships- Dalaric...is dead. Klaroline...is dying. Deremy...missed its time. Steroline...is hindered 由 Stelena. I know Stefan is the 'good guy' and if he managed to stay on the wagon he wouldn't be bad for Elena in the long term either. But does anyone really want to see 更多 boring love? If 你 do, are 你 sure 你 want to see two 更多 seasons of boring love? Maybe it's good in real life. Maybe it's good for your friends. Maybe it's good for your neighbours. But it doesn't make good television.
Character growth- Stefan had his redemption arc. Matt's acceptance of the supernatural. Alaric letting go of his past. Jeremy becoming a Hunter and making sacrifices. Katherine had hers quite recently. Klaus is going onto the new 显示 for his. Rebekah's feelings for Matt, Bonnie's Shane arc and post-Shane story (and let's not forget her disastrous 爱情 life), Caroline's transformation from nasty cheerleader to loyal friend and teammate. And of course Damon, who has suffered and grown 更多 than anyone else, through all 4 seasons. Who's left? Elena. And she won't grow as a character if she keeps picking the 安全 option.
The Blood and Badassery- So think of it this way. It's a vampire 显示 and we thirst to see blood. A lot of blood. And let's face it- if Klaus and the Originals are gone and Damon goes soft trying to impress Elena, we aren't going to see much of that. On the other hand, if Damon brings Elena over to the dark side...blood! Blood! Glorious blood, they're not humans with superpowers anymore, they're bloodthirsty vampires! Which was the concept of the 显示 to begin with.
Damon- I think it's 安全 to say that Damon's the funny one on the show. The only funny one on the 显示 now, because Elijah has gone god knows where, Katherine has gone god knows where and Caroline is too busy making Stelena shirts. Damon, at his best in the first two seasons, is the 心 and soul of the show. If he dies, the 显示 dies. And if he has his 心 broken again, all we'll see is another pointless killing spree. I know that my last point was about blood, but death is a 给 on TVD and it doesn't count unless it's a character we love. They're hot model 吸血鬼 after all, not dracula i-vant-to-suck-your-blud types.
Delena- Because they have such amazing scenes, chemistry and your eye is just sort of drawn to them. Even if you're a 粉丝 of some other pairing, 你 have to admit that their friendship (and thus any interaction between them) is screwed if she rejects him again. So if this goes, the 显示 kind of strays into the good story, but meh category. 你 know, the shows that people watch only when there's nothing else on TV? That are interesting, but don't really grab your attention enough?
Spectacular writing- They kind of derped with the Sun and Moon curse (which was fake, ha!), but they've had a pretty spotless record when it comes to making sure everything is not only canonically sound but also genius. But the 写作 kind of went down the drain with the sire bond. Seriously, there were too many plot holes associated with it like the fact that she was able to defy him in a few episodes. And how many times are they going to pull the it-was-fake card? Seriously, it only works if 你 don't see it coming.
Quality of the actors- Which will still exist, no matter who Elena picks. But nobody watches a 显示 just because of good acting. At least, the majority doesn't. And in TV shows, it's all about the ratings.
So in truth, the decision to drop the 显示 has been in the back of my mind (and this might apply for some other people too) for some time now, but I've been clinging on to the hope that TVD, Alloy, Julie, Kevin, anybody can pull it back from the cliff before it's too late. If Elena chooses Damon, it shows me that they're getting back on track. Why? Because it would be unrealistic after a season of her proving her genuine feelings for Damon for her to pick Stefan again!
Personally, I won't be leaving entirely. I'll be watching from a distance to see if all is 迷失 或者 if there is a sudden burst of awesome for the show. But I don't blame anybody else for quitting because there are only so many ways the 三角形, 三角 can be recycled.
