Don't agree. First of all, videos give a good impression of the animations ,second, feedback is important for the developers as a reference of what people like or don't like. And as it has been said before, criticism here is constructive, not discouraging.
Now, back on topic: I just watched the G4 Hands on and the Walkthrough video from the other thread. Looks really cool, especially because in those two vids we see the different play stiles (combat vs. stealth). I love the way, the target reticule narrows in slowly when you try to archive a critical hit.
But what people said here is true. The animations are way too fast. That really takes realism out of the game. I hope this will be polished until release. Other than that, it looks pretty much like I expected it. In other words, it's gonna be my personal gaming highlight of the year.
