Does gears 5' campaign get better?

I'm on act 2 chapter 2, I just reached the first open word area. I'm not impressed honestly. 4 impressed me at first more then 5 so far. Also even on advanced I'm noticing there's barely any flanking, by me or the enemies. The enemy AI seams bad, like they just charge me a lot instead of using cover or trying to get around me. So just staying behind one area of cover for the most part is what I do, not much need to change cover a lot which is how I like the shooting in this series.
