Bloodsport (1988)

VD travels to HK for a three-day illegal martial arts tournament known as the Kumite. Between bouts the script has him stumble through clichéd flashbacks and musical montages. He befriends a fellow fighter (Donald Gibb) and gets involved in a passionless relationship (Leah Ayres) that's as dull as twitter.
The action star's speed and physicality is impressive, especially the eye-watering splits, but the more important aspect — by that I mean the acting — is pathetic. He's not alone in that, however, because about 90% of the (English language) cast are as bad. Often the editing isn't much better.
The main villain is the most memorable character. Played by Bolo Yeung, his two-dimensionality works in his favour; well, until he gets dialogue.
