You have a strong leading duo with lots of TV experience and so their acting ability and chemistry is strong. They clash because she's the new one coming in with strong opinions on how she should work and how others should work. They do care about each other as well. The rest of the cast does a reasonable job with their roles too. Unlike a lot of TV from Hong Kong right now, I feel this TV Show struck a good balance between comedy and touching moments even if sometimes the comedic moments were a bit over the top for my liking. There is romance but the overall show is about the team solving cases and their police work. The cases are sometimes used to make social points and some of the characters themselves struggle with problems such as the potential of being a single working mom. There are some good life lessons in this show. I give it an 8/10. It's not going to blow you away but I think it's a good show and worth giving a chance to.
