This is a real gem, 50 minutes of pure joy and brain-massage, ahhhh.
In a nutshell, it's Terminator gone animated, with a cutesy cast and some great fights with the killer robots - keep your overblown plots and twists which don't make sense, this is what entertainment is all about. Military VS murder machines, what a result! If nothing else, watch this once for those few scenes - some of the best sci-fi combat I've seen on any medium.
Although it's a only a short-film, there's nothing to really go wrong and the pace is so fast that you're too busy enjoying the ride to get nitpicky.
If you like sci-fi anime, Masamune Shirow or wearing a smile then this is headed for your DVD collection.
