"Ninja" does something that is hard to do.... it updates something from the past but still retains a nostalgic feel about it. Sometimes it felt like it was 1985 and I was a kid sitting on the living room floor eating popcorn and watching American Ninja. But then I see Scott Adkins do an amazing aerial kick and I know I'm not watching Michael Dudikoff. "Ninja" takes a similar formula and story from those ninja movies from the 80's and combines it with a hard hitting and acrobatic fighting style seen in today's martial arts movies. This movie was a lot of fun and if you grew up watching ninja and martial arts movies in the 80s like me, you will definitely enjoy it.
