1 (Original's the best by far. Thankfully wasn't campy) 2 (Dudikoff and James return. Fight choreography sadly takes a turn for the worse. Drastic change in tone, but still fun) 4 (Bradley doesn't come off quite as horribly as he did in 3. Dudikoff's back for only minimal screen time, but it's great to have Joe Armstrong back. Extremely low budget but hilariously deadly serious: "He's also a fantastic bowler, but this is not a game, Gavin. THOSE WERE NINJA!!!") 3 (One of the worst sequels of all time. Unbelievably bad. Worth watching for Steve James) 5 (Couldn't even make it through it. Horrible. A sequel in name only)
II (Hilariously bad + Dudikoff!) III (Hilariously bad) I (this was NOT campy and bad enough for me! Good movie though) IV (It was OK) V (Pretty damn bad, but not unwatchable)
