It did not help viewing it in an English dub; bad dubs by themselves are not enough to save a film, and it also removed any of the diegetic sound (maybe even the original music) bar a cheesy synth score it might have originally had. The content itself does not muster enough to be a good or at least entertaining film. Aside from projectile vomit as a weapon, and an improvised episode of head swapping operations, there's little in this to care about it, compromised by the dub even more.

Henry Sanada and Sonny Chiba play ninjas. That's all you need to know.
