This movie is no where near as terrible as everyone else makes it out to be.
The dialogue is indeed terrible, as are many of the lines. The plot is somewhat silly, and the acting ranges from mediocre to corny. All this and more make this a movie worth watching.
The opening scene is an absurdly funny gun fight (whether or not it was meant to be) including a guy pulling a bazooka out of no where to kill someone for a 3rd time. Also present in this scene are needless backflips, and the overused wooshing noise that gives this movie character.
The whoosing noise was most definetly added in in jest; no director would ever think it serious to have a woosh when someone nods their head, and the overuse of this is hillarious.
Most of the movie takes place on an island where one spark would cause a giant explosion, so they fight with swords and the like. Yes, the swords would create sparks that would cause an explosion, but they had to set it up somehow so that the melee scenes could make sense.
And the fighting is some of the best seen in a while, with weapons ranging from chains, an acidic paintball gun, and a scarf. How many movies do you see where someone actually gets beaten up with a scarf that goes "woosh?"
Not a film for those who like to think deeply into everything they see, US Seals II is nothing more than a Western Hong Kong film, whose plot mostly serves no more purpose than to provide a catalyst to bring on the amazing fight scenes.
And as every single other review points out, the main bad guy did indeed have a cigar in his mouth while in an island that any spark would blow everything up. What every other review does not point out is the fact that the cigar is not lit.
