So this is a good example where all the parts are there, but it just is missing something.
There are some very talented acrobats in this. There work is very good.
There is a bad guy who is too smug and doesn't really have a history of why he roaming around beating up every person that says they know kung fu. He just does it. Which doesn't make him a very engaging villain.
Classic get beat up by bad guy, go learn (another) kung fu and come back to confront the bad guy.
This has three student going off to do that with different instructors. Two of them have some detailed training sequences, not so much for the third.
Meanwhile their teacher is up to his own studying which isn't gone on into. And a trick that isn't explained how he came up with it or devised it (trying to avoid spoilers).
Needless to say, there is a lot of leaping and jumping around.
This one is low on weapons play, but there is some.
Honestly, I had to put up with it to watch the whole thing, and that's a shame. The elements were all there, but they just didn't really come together like those same elements do in other films.
