A whole lotta pointing with no shooting
First of all let me make it clear that I'm no newbie to the gantz universe. I've been a fan every since the manga first premiered and I've owned the anime for a while now. That being said I understand that both of these other formats have their flaws too, especially when it comes to confronting aliens in the beginning of the series. But something about the movie really work my nerves. For example,"an android is running at you full speed and you already have your gun pointed at it with your finger on the trigger." What do you do run or shoot. It seems our heroes would most likely run first then shoot later. It happens again at the end when Kei is getting his legs sliced and diced and the girl Kei decides to just point and... turn around and run once Kurono is dragged to safety. Now I understand that this movies is coming from a country where guns are virtually non existent, but come on this is just too extreme.
Other than that I can say that its a pretty decent adaption of the manga and its slightly less annoying than the anime. So if you're a fan of gantz then this is still a must see.
