This list contains characters I think deserved better endings and/or treatment throughout the shows they are a part of.
1. Anna, George, Beth, Cordelia, Dean, Hayley, Keith, J.T., Marissa, Quentin and Elijah - They shouldn't have died at all, or at least not how they did.
2. Haley, Robin, Sheldon, Blair, Jackie, Lane, and Rachel - They shouldn't have ended up with who they did, especially considering they all had to lose character development to do so.
3. Bernadette and Penny - Ugh. Neither wanted kids and were firm on te fact, but because their husbands wanted kids, they were made to have them by the writers. Absolutely disgusting.
4. Toby and Jerry - They were treated like crap and were the butt of so many jokes. It's less funny and more sad when you really think about it.
5. Bonnie - She deserved better treatment throughout the show and a better/happy ending.
6. Kira and Isaac - They didn't deserve to be shipped off and forgotten.
7. Regina - She deserved to be happy with Robin.
