Depends on what you want out of it. Watching a movie about martial arts is not very different from watching sports. They just add a stupid pretext why the guys have to fight each other. If that's what you want to see, you'll be happy.
Otherwise, if you think a movie is a somewhat wider art form that is supposed to have certain characteristics, like a proper story, credible acting, a meaning etc, then you won't be satisfied.
Personally I never go for the first type anymore, I did when I was a kid though.
