Look, if you walk into a performance review and you don't know how it's going to end, your manager is doing it _wrong_.
Your manager should know your strengths and weaknesses. They should know your successes and failures and _why_ they were successes and failures. They should know your goals and form a plan for you to help you accomplish them (a serious plan, not some "well, they make us list three goals every year" crap). The only way to get that is to have open, frequent communication with you.
A good manager is there to help you succeed. If not, they're just a boss.
