This was another great match. They did a very nice job of establishing all the competitors on an equal level, with no one getting the clear upper hand or looking that much dominant...
... at least until Braun appears. Then the match kind of turns into a game of survival, and that's what it's all about until the end. Braun is put over not as a Kane, or a Big Show, who got beaten by joint efforts in previous Chamber matches. Instead, he is put over as someone that even if you manage to pin for the three count, you are going to lose. Him kicking out of a dozen finishers and eliminating five people, one by one, was scary as shit, when you think about it.
He was like Jason Vorhees and the other guys were the designated victims.
But the match wasn't *just* about Braun. You had Elias being a smartass trying to make good use of his last entry position and picking up the scraps, and you also had Cena in a rare moment of despair, because his road to Wrestlemania might lead to a dead end.
You had Balor getting a HUGE shine against Strowman, and Reigns/Rollins are usually very good with their friendly foe dynamics.
In the end, Roman's victory ended up being a feat of survival, a fluke, more than anything else. Like Sarah Connor crushing the T-800 on the first Terminator. I dunno. Some movie reference.
