It looks like to me you never had to do code reviews before, then management decided to push mandatory code review down your throat while migrating to git. Now you have to learn to do code reviews AND to use git AND to do branching, at once. No wonder it's overwhelming. Code review is normal software development in all companies. Though if your team is small (somewhere less than 5 developers), it's better to make reviews optional, there's never anybody available to review. As for git and (git) branching, you will have to learn because that's what the industry standardized on. It's a shame because git objectively sucks (it is terribly user unfriendly). You have my deepest sympathy.
