Yea, if my catastrophe could've spared Eli, I would've made the effort. Park, yea, she was usually pretty alright.
Greer, I hated him, he was so arrogant and had such a large chip on his shoulder, until he got trapped in that underground Earth Military base. After that, they developed his character, and I liked him more and more each episode until the end.
Rush, when he came back, after the Rebellion, he was much easier to take. I really liked him
by the End too (And I've loved Mr Gold/Rumplestiltskin since the beginning on Once Upon A Time)
. I also liked him alot in Heroes
