Mass Effect 2 legit has better facial animations than Andromeda in many ways. The biggest issue with Andromeda is not really the facial animations, they're quite OK. But the Eyes are extremely 'dead', like there is no glint from them, they don't refract light right and don't twitch/move around at all really, or go way overboard with the movement. If anything, the eyes need to fixed to get it most of the way out of the uncanny valley.
EDIT: The eyes also are just WAY TOO HUGE. Like Anime Eye almost. If you check the nose to eye ratio the eyes are just too big.
