The impression is fresh for a while. What is the first thing you do?
Do you discuss it? Do you write some kind of review for yourself? Do you explore professional reviews/analyses instead to compare the perspectives? Do you give yourself some time to form an opinion? Do you do something else?
Same. It’s also helpful in remembering the plot later if there’s a sequel or two. The only time I don’t do this is when I know I’ll want to re-read the book later, so I will actively try to forget parts of the book. That way, it’s a fresh (well, fresher) read when I get back to it.
