My first impression was this is waaaay too red. If anything it's possibly even more red then the RED trailer. Like I know it can't be all black(that would make things hard to see) but it was definitely too red for a "Black" trailer/character. Like least in the RED trailer them showing a lot of red makes since since she was slicing up a bunch of living creatures that would obviously bleed, but here they're fighting all robots, where black would've actually been made more sense. Oh yeah I decided to watch the RED trailer again, and it's really white to give the red a chance to stand out, which I'm guessing they tried to do the same here but didn't work out nearly as well.
The voices was ok, not great but not too bad either. The talking however wasn't all that necessary. Really most of the lines didn't need to be said at all, they just needed them to say a reason to split the two up. (the whole one is willing to kill innocent bystanders and the other isn't thing) Which makes me wonder why have them as a pair to begin with.
Speaking of which not a big fan of the guy either since he took up too much of the spotlight, mainly by saving Blake like twice and getting the killing blow off the boss whom she wasn't all that useful against. Made her feel like the sidekick when it was supposed to be her trailer, especially since it felt like he was in charge of whatever mission they were doing.
The music was interesting, different from the other 2 which is good for variety sake.
And I have no idea how her weapon works, is it gun boomerang whip thing that she can use to cut things while somehow still pulling the trigger to shoot stuff? I guess it's a neat idea but hard to see since it's small and moves really fast.
Overall this is probably my least favorite trailer of the 3. Still great work but I don't think I'll be rewatching it nearly as many times as I did the other 2.
