That was a good trailer on its own, but "Hurt" by Johnny Cash makes anything more epic. --- Sazh: "You don't look ready to go quiet into that good night." Lightning: "You want quiet? You better take the next train."
It's up on Youtube for those who haven't seen it. I thought Mercer looked really off as well. They definitely didn't cast him well. Also the part where he just pulls up his hand and it's a claw and then Heller does the same thing.. it looked really cheaply done. They could've added a few VFX in there and showed their hands transforming and it would've looked 1000% better but they took the easy route.
