While the fights themselves are good, they do drag on a bit too long at regular moments throughout the movie. Injuries don't seem to have any ongoing consequence for more than about 5 seconds. It's as though they shot a lot of the action such that they could mix up the order of scenes in post. They also just swap and change between who is the dominant fighter and who is the lesser fighter for what seems like shits and giggles. Just to protract the fight, nothing more. There's no reason for who has the upper hand changing as most action and fight movies seem to do (including what should be ongoing injuries but somehow even stop bleeding when they really should have bled out). All of these just seriously take away from what ultimately is good fight choreography.

Having Andrew Koji mostly with guns is a waste of that actor's fighting skills as seen in the TV show Warrior.

As for the plot, it's an action comedy. It doesn't need to be good nor solid. Don't overthink it.

Ultimately, cutting a few minutes out here and there would have helped, as would more intent behind injuries & reasons for fight balance changing.
