In a giant sea of blaxploitation films, "TNT Jackson" doesn't stand out from the crowd other than its setting and gender of the protagonist..and its copious nudity. Otherwise, it's a standard cheap action film of the 70s and not a lot more.
Ex-playboy model Jeannie Bell stars as TNT Jackson, a lovely lady from Harlem who has ventured to the worst part of Hong Kong in order to discover what's happened to her brother. Apparently, he got on the bad side of a organized drug ring...and she soon gets their attention. To help her is a local Chinese man as well as an undercover federal agent.
The martial arts are spotty...though the double who does all the acrobatics for TNT was very good and it's very hard to tell that a double was used...so kudos for the director for this. Unfortunately, in the close combat scenes, they are spotty...from pretty good to pretty bad. As for the story...it's all pretty tandard stuff apart from the setting (Hong Kong). For fans of the genre, this one in't bad but it certainly won't convert anyone to the genres of blaxploitation or martial arts.
