I have no idea why this movie is so low rated, it was very in tune with the entire Gokushufudo series. If you liked the drama, you're going to love the movie.

It's an action-packed movie that put a lot more effort into some action/battle scenes, but that only adds on to the best part of the movie - you can actually physically see actors have fun making this. I'm sure that the weapons store scene was chosen because they legit couldn't film it without breaking character. It was funny, comfy and expectedly unexpected in some parts.

Treat yourself and watch this movie :)
