I think I enjoyed the movie more than the other HKMDB reviewers, but then my expectations were quite low. Sure it's rough around the edges, but it's worth watching for the great displays of acrobatics and some decent action scenes. It's not first-grade by any means, but more interesting than most of the action that HK has produced in the last year or two. Donnie Yen looked like he wasn't trying at all though.
I assumed the movie was made in mid-80's when I watched it - feels about 1986. Maybe it just doesn't live up to expectations for a more recent movie?
