I have not seen the original Kung-fu although I have seen the sequel series, The Legend Continues so I have some familarity with that.
I thought Evan was used a little heavy handed too. They obviously want to set up a potential love triangle with Nicky, Evan and Henry despite Evan having a girlfriend already and Nicky up and leaving for 3 years on a whim. And Henry? Something seems suspicious about him. Feels like they are setting him up to have a big secret.
The way they put her in the temple was clunky as all get out too. Her mother setting her up to find a husband in China only for her to run and hide felt like a lazy cliche and almost like the setup to an entirely different series. I was borderline bored and rolling my eyes through the first part of it. Once they progressed the story some though, especially closer to the end, it got more interesting.
The one thing (ha) I found a stretch besides the mystical subplot is how she became a kung-fu master in only 3 years. I don't think she needed a lifetime of training by any means but in 3 years she is now good enough to take on all these presumably better trained fighters and hold her own? I guess she practiced a lot.
I'll still come back for episode 2. I am not going to write it off just because of some minor issues. They have room to grow.
