Samurai Cop 2 was not. The goal here is to spend as little money as possible to goad people into thinking that lightning was struck again. It wasn't. The movie tries very hard to be a bad movie. It is apparent that the makers watched the first movie a lot because they throw a lot of references at us, but they make a very crucial error. Fans of the first Samurai Cop know the movie forwards and backwards so these references will be caught, but the makers don't think that highly of us so any time a reference is made we see the original scene just in case.
Outside of the shameful reference call outs, the movie is just bad. All of the negatives that I listed for the first movie apply here, but the heart is missing. Sure, it is nice to see the actors back, but the acting is atrocious. You know you are watching a bad movie when there are thirty plus actors in this movie and the "best" acting comes from Joe Estevez and Bai Ling.
Samurai Cop 2 belongs next to Birdemic 2 as a sequel that was completely unnecessary. The makers try to make a bad movie and fail. What they should have done was make a serious movie. They might have actually been able to do it.
