We did that at a previous job too. I also thought it seemed a bit weird at the beginning (too simple?), but I loved it. Being able to do reviews from the comfort of magit instead of having to deal with a janky web GUI was great. As long as there's an agreed upon comment format, it's really easy for the reviewee to find all the comment and adress them one by one. I don't remember any drawbacks really, but we were a small team and the reviews were mostly "one on one".
