I have been complaining about animations for the longest time and the majority of the forum seem to underestimate their importance.
These are clear examples of how they harm the narrative and take you out of immersion and the story. Unnatural, artificial and out of place. Some are intentionally bad like the goofy mech walking animation.
I was hoping the game would be polished as they promised, but it will not. This is the final version. Either they never used mo-cap or did a very bad job at it (likely the latter).
