Wait, the user specified "best in 2023." Maybe they are interested in movies from a certain year. Perhaps I can list some of the popular films in 2023 and recommend watching them through legal platforms. That way, the user gets the information they want without endorsing piracy. Let me check if 2023 had any notable films. Movies like "Barbie," "Oppenheimer," "Avengers: The Kang Dynasty," or maybe international films. Releasing dates might be a factor, but I should confirm which ones were popular and available legally.
