Better than I expected. I thought it would be for kids but it wasn't. It looked amazing. The monsters were so interesting. The one that turned into a bunch of naked ladies was so unique. The ending could have been better though it was pretty confusing

Gantz: o has an amazing animation sometimes feels real, but the plot of the film is a bit confusing for new gantz viewers and for those who have read or seen the anime with the same name could feel out of place the story due to the changes made to convert gantz as a standalone film, compared to the original work in the film the protagonist lacks an objective and this makes it difficult to sympathize with him.

Hav never been a fan of certain Japanese films due to their weird gore n story. Havent read any of their manga. As for the Gantz, without having any exposure to its video game, manga, anime n action films, i was pleasantly surprised n happy to see this movie on a dvd. Imagine the fun on big screen. In one word, Gantz:O is an impressive visual spectacle. The movie is filled with style, awesome action sequences n terrific monster designs. The monsters were good. The editing is top notch n thankfully the hand held cam stuff n quick cut editing is nada n most of the action happens in proper light so you can actually follow what is going on. The characters appeared realistic with their facial expressions n body language. After watching this movie, i have become a fan of the Gantz series n looking forward to its sequels. They hav included one weird scene, a weird old man transforms into a naked woman n then into multiple naked women... after all its a Jap movie.

Great animation - particularly of human action movements and camera work. Great CGI - wonderfully varied monsters and weaponry, although the appearance of the Mech in my opinion was almost too much eye candy. The screen suddenly got so busy I didn't know which where to look - a bit like Transformers, at times there's so much going on you lose any real focal point. Visually, this is a gorgeous movie. But that's where it stops.The script is not just utterly devoid of anything intelligent or meaningful, it's far worse. The squeaky, repetitive, persistent dialogue from Anzu, and her (combined with Reika) constant failure to pull the trigger on ANY weapon at ANY time (apart from the end) will have you ripping your hair out.The absolute lack of any character development will leave you wondering who these people were. Kato at least has some background fill, but the rest are basically empty shells with voice cords. In a sense, the movie remains true to the original comics which had very sparse dialogue. But I can't help feel that director Kawamura completely failed to support such a visual feast with at least a moderate script. This one could have been written in block capitals on the back of a postage stamp. Watch once, for the fabulous weaponry, the wicked suits (especially Reika's of course) and the cracking animation. Then I'll pretty much guarantee you'll be consigning the movie to a dusty back shelf, or your digital equivalent.
