Though I agree to a certain extent of why you don't like this movie, you have some pretty weak reasons why. "you barely care about the family murdered in the beginning". You are not supposed to care about the family, you are supposed to care about Costello. You are supposed to bond with him, Kwai, Chu, and Fat Lok as a team. "his amnesia never presents itself at all until the end of the movie, and Fung just suddenly realizes he has it with no explanation how." Costello takes pictures of Kwai, etc. because he cannot remember. The amnesia doesn't get really bad until the end, after having shot at Fung (meaning he knows what he looks like), that he needs the sticker to remind him who Fung was, and since Fung is a smart guy (BOSS!) I'm pretty sure he doesn't need someone to tell him that Costello has amnesia. This movie has many similar themes to other Johnnie To movies, and although it's not his best work, he does a very good job. If you don't like the English dialog because it's not perfect of "silly" go move to HK and help them make a better script and teach them better pronunciation. Also, remember this is a French/Honk Kong production, not an American one, so things like "serious crimes unit" are OK, since most of the target audience doesn't speak English as well as we do. They don't know the difference, and it really doesn't matter. Check out To's other films, like the Mission, Exiled,etc. if you haven't.
