I still think about how good the Rollins/Ambrose feud was all the time. I could watch a hundred Raws that revolve around Ambrose popping out of set decorations and then hitting Seth Rollins a lot. He had a purpose and it was golden. His character made sense. Dean Ambrose is unstable but likes friendship. Seth Rollins was Dean's friend, but then Seth was mean to Dean, so Dean wanted to hit Seth really badly. He always power-walked to the ring because he was so excited to hit Seth Rollins, over and over and over. He would see Seth backstage and try to hit him because he's unstable and he didn't care about the context in which he hit Seth. He just cared about hitting him, a lot of times. And friendship.
Then Bray Wyatt became a smoke genie and, well, you know.
