After V for Vendetta, James McTeigue fans had great expectations for his next project. Sadly, it didn't come to be as interesting as it should have been. The plot's abysmal at best and the characters are washed up and bleached versions of better protagonists. Granted the script wasn't written by the Wachowskis, but that alone should have sounded the alarm that something was wrong. There's loads of blood, even the question of how "superhuman" the ninjas actually are, but no question you can ask yourself will be answered, be it in-depth or even scratched.
The features don't show much either as you get the usual Warner extras. In a word: less than twenty minutes worth of it.
Glad I didn't pay over $5 for that.
