Detective Chinatown 2 is not quite as good as the first movie, but it is still laugh out loud funny and entertaining.  It still has the same classic, ridiculous humor as the first one.  Watching the main characters run around New York trying to solve a murder mystery and landing themselves in ridiculous situations is worth watching.  Add in the cast (some old, some new) and some fun music and you've got yourselves a solid good movie.  The actual storyline part of it was a bit weak considering there were a lot of characters and a lot going on, but it was still decent overall. Although this is a sequel, you do not have to watch the first movie to see this one.  You might miss out on a few jokes, but it wont affect your understanding of the plot at all.
