American Ninja 2 is not a good film in the traditional sense. The acting is hammy, the action sequences are corny and the plot is kind of stupid... yet, that's what makes this movie so entertaining for me. Plus it helps that I used to watch it a lot when I was a kid, so it's also got that special attachment to me.
There's plenty of giggles to be had, some intentional but plenty unintentional. This is a good film to watch if you're in the mood to just sit back, chill and give your brain a 90 minute break.
