I got a question in my review queue, saw a bad answer, and downvoted it with a comment politely explaining why. The answerer politely told me that his answer was more appropriate before the question was edited.
What's the right thing to do?
A) When looking at things in my review queue, should I just focus on helping produce good answers and never downvote existing answers? No matter how bad? I am new to review queues.
B) Should I remove my downvote? Should I encourage deletion of the answer? Regardless of the history, the answer is now poor.
A typical case is where a question is too general. The community provides comments that help OP improve the question, while others answer the general question with general answers. After the question improves and receives better answers, the early answers look really bad. They look evasive, even flippant.
What's the right approach? Again, I am new to reviewing; I just began getting these prompts to do it.
