Well, I have put in a few hours on it now via Origin pre-access and it isn't all bad... but it sure as hell isn't great either. The good is that the combat flows wells, the AI is decent on both the enemies and your team-mates, and the environments are very well made. The bad is, I really can't recall ever seeing such poor character models and animations in a triple-a title... At least not one where they were obviously trying to have lips-synced and psudo-realistic movement. Couple the jarring visuals with painfully weak dialogue and a pretty non-compelling story so far and ugh.
It's pretty disappointing. I was such a huge fan of the franchise I replayed the previous three in anticipation of this game -- hell, I didn't even mind the MASSIVELY maligned ending to 3 that much.. but this game is disappointing so far.
With the combat seeming solid the multiplayer will likely be decent (have not tried it yet) and I like exploration so I will probably drag my ass through it to the end, but this is certainly feeling like a mediocre-at-best game.
