Of the John Woo films I saw, 'The Replacement Killers' and 'Bulletproof Monk' were pretty good, both of which starred Chow Yun‑Fat who I really like. A couple more great Chow Yun‑Fat films I would recommend watching are 'The Corruptor' and 'Crouching Tiger, Hidden Dragon'. (There's more, but I don't want to make this post all about him.) Regarding the other Woo films I saw, 'Broken Arrow' was alright, but I didn't really care for 'Hard Target', 'Paycheck', 'Face/Off' or 'Mission Impossible II'. Although the original 'Mission Impossible', directed by Brian De Palma, was great.
