Absolutely killer concept poorly executed. The manga is too obsessed with the monsters. The movie is obsessed with emotional moments and they never pull the trigger. The anime is not bad in terms of the balances of plot and character, but it was definitely a rushed job. BTW, the picture is not from this movie.
Like "Death Note," this is a lengthy, two-part live action adaptation of a popular manga/anime. Unlike "Death Note," "Gantz" treads more into pure sci-fi territory, combining elements of "The Matrix" and "Men in Black." The movie version wisely tones down the more "ecchi" (sexual) elements of the anime but keeps the blood 'n gore intact. Overall, I was thoroughly entertained and look forward to Part II.
I was hoping GANTZ would be one of the very few manga-to-live action adaptations that would be worth watching. It is not as melodramatic as one has come to expect from Japanese blockbusters, but many moments of over-acting and stiff dialogue are still there. GANTZ is one of those rare moments where you wish the film team took more liberties with the source material. Very boring.
