I don't really have a problem with a movie that's a rip-off as long as it is competently done. In this case, the movie being ripped off is "The Amateur". While that movie had some problems, it wasn't boring and at least kept moving. "Ministry Of Vengeance", on the other hand, takes forever to get going, was obviously shot on a low budget, and isn't the least bit exciting. Too bad, because it gets off to a promising start with its showing us the grief and rage the protagonist feels (though soon he turns bland.) You could do worse, but you could do better by renting "The Amateur" instead.
