The Titanfall comparisons are a bit lame to me; but the game looks a lot more 3rd person focused than that, so it's not the worse thing.
Why does everyone have to wield guns in EVERYTHING? I like that he actually pulled out a baseball bat for his ground pound, at least; I hope there's a few things that aren't just shooting. The Ratchet games always had fun guns though, so if it's gotta shoot, I guess they're in the right hands.
The animations don't bother me. They look "Gamey", in the fact that they look like they're concerned about precision and intuitiveness first, and making it all work in 3D second. Also, with Create-a-Character being a big factor, they're probably not focusing on making character build-and-body specific animation just yet, but instead, unisex, uniform animations that could work with any type of person.
The open world element does nothing for me, specifically. Open worlds with no "life" to their surroundings might as well just be games with specific stages, to allow for tighter design structure, and more varied elements. But the idea that the game is SOOO different at night intrigues me. Dead Rising 3's ability to make nearly each and every building enterable and unique gave worth to the open world.Red Faction Guerrilla's world destruction made it like a playground of adult building blocks. But so far, this looks like a classic "they might as well be boxes in 2D platformers" approach, which is a bit disappointing.
All in all, I like what I see, though it'll have to push even harder to really sell me on it. If they can give the gameplay as much personality as their "BOOM" explosions, then it should end up being a treat. It feels like a "Sunset Drive" at this point, lets hope the rest brings the "Over" into play.
