The original Gamera series quickly aimed for the 5 to 8 year old set after two attempts at the standard "adult" monster film typified by the Godzilla series (although these kept lowering the age bracket with each film). Gamera films usually revolved around turtle loving children put in peril by aliens until their rescue by Gamera. The children sometimes would help Gamera either by cheering him on or in a more disgusting case, going into his body and fighting a parasite infection. Strangely, the original Gamera films features more gore and gross damage to the monsters then the Godzilla films ever attempted. The revived series directed by Shusuke Kaneko featured a more mature approach although Gamera had a psychic connection with a teenage girl. Kaneko also introduced a more integrated approach to the kaiju genre and raised the bar for all kaiju films. The re-revived series has aimed to return to Gamera's roots in the 1960's, once again presenting Gamera as "friend of all children".
Director Ryuta Tazaki comes from Japanese sci-fi action television with quite a resume with the Japanese Power Ranger Shows and never ending Kamen Rider series. This film shows little of his TV roots as this film is very well directed, well photographed with some modest experimentation with visuals and sound design. The film has a sort of naturalism that you don't usually get in a kaiju film. The hero just lost his mom to a car crash and his friend is afraid she won't live thru a heart operation in the hospital. THe parents are working class shop owners. A few moments of over-sentimentality and cuteness are here but the rest of the film makes up for it. The special effects live up to the level of the Kaneko Gamera films with a couple of shots that are excellent. Tazaki doesn't have Kaneko's dramatic flair for the action scenes but they are well done. As a note, this film does have some rather gross green gore when Gamera is hurt during the fights, this may upset children here in the west.
Once again Gamera sets a high standard. Recommended.
