Review: What if a platoon of G.I.'s from the Japanese army were to be send back in time 400 years right in the middle of the feudal wars that led to the formation of the Tokugawa Shogunate? Great pitch right? The movie does exactly what it says on the tin.Thankfully the writers didn't bother to explain the, usually ridiculous in sci-fi movies, scientific mumbo jumbo of time transport. No how's or why's. They just did. However the time transport sequence itself is trippy as hell and quite beautiful, if not a bit dated. Not as silly as one would imagine.The rest of the movie follows the premise to a T. But while it loses a bit of steam with the various subplots that follow the G.I.s arrival to medieval Japan, it picks up with a devastating battle sequence. Undoubtedly it's the main order of the day. The whole concept and by extension the movie itself, was probably originated from this simple pitch: what if G.I.'s equipped with the latest in modern warfare were to fight samurais? And boy does it deliver.The main battle sequence that spans more than half an hour is probably one of THE best of its kind in 70's action/war movies. Not only is it relentless and exhausting in pace and length, it's also a terrific mish-mash of styles and techniques that only unique premises like G.I. Samurai can deliver. I mean, where else would you get the chance to feature tanks, ninjas complete with shuriikens, a helicopter and samurais in the same shot? The G.I. platoon led by lieutenant Iba tears literally through hundreds of extras, gunning them down with machine guns, mortars, grenades and tanks.This mish-mash of styles is with one foot firmly rooted in the sprawling jidai-geki epic of Kurosawa's Kagemusha or Hiroshi Inagaki's Samurai Banners, while the other is in western action and war movies. There are stylistic touches (like the wonderful slow-motion shots and bloody violence) that bring Sam Peckinpah or Enzo G. Castellari circa Keoma to mind. Japanese cinema has always been influenced by westerns and other Hollywood works and vice versa, and G.I. Samurai effortlessly turns this east-meets-west melting pot into an exciting film.The film-makers thankfully take the whole thing seriously and the movie benefits immensely from it. Not that tongue-in-cheek mentality is completely absent, it's just that it doesn't try to pander to so-bad-it's-good audiences that enjoy laughing at their movies. The budget was probably hefty, as it is evident in the hundreds of extras, elaborate costumes (very decent for a production that is not a traditional jidai-geki) and special effects. The camera-work and editing are all top notch, almost better than a movie with no higher artistic ambitions deserves.It's not withouts its flaws either of course. There are many "song" scenes, where all sorts of 70's Japanese rock, disco and country songs play over montages (there's a bonding scene, a love-interest scene, a "war is hell" scene etc). The songs themselves are pretty lame and corny and detract from the whole thing. Although it clocks at a whooping 140 minutes, it flies like a bullet for the most part. Still some scenes, flashbacks and subplots in the first half could have been clipped for a tighter effect.The cast also deserves a mention, featuring such prominent names as Sonny Chiba, Isao Natsuyagi (Goyokin, Samurai Wolf), Tsunehiko Watase (The Yakuza Papers) and Hiroyuki Sanada, all of them hitting the right notes. Question: is it a negative review?
no

Review: very badly made film, the action/violence scenes are ridiculous.1 point for the presence of Burton and Mastroianni + 1 point for the real tragic event of the massacre of the innocent italians: 2/10. Question: is it a positive review?
no

Review: I realized a couple of days ago that the makers of this film put a play on words into its title. This movie is not primarily about the act of "riding giants," but mostly about the people who are the giants of the sport, RIDING giants, to change the emphasis.In my teens I lived a block from the Wedge, one of the hardest-breaking and best bodysurfing spots in the world. I've been out in 15-to-18 foot surf, and have ridden and been hammered by 10 and 12-foot waves on many occasions. That experience is why I am in complete awe of the surfers in this film. The idea that Jeff Clark, to all appearances a normal mortal, could get away with riding Maverick's BY HIMSELF for over a decade is beyond my grasp. The first safety rule of any water sport is "Never surf/dive/swim by yourself." He went where sane people would not, and lived to tell about it. I wouldn't go out there if the water were 75 degrees and the sharks all left. In the world of warm water: the first shot of the waves at Jaws always makes the skin tingle over my entire body. These are not just scary waves, these are uncontrolled-bowel-evacuation waves. When we see Laird Hamilton not only surviving 40-to-60 foot waves (I can hardly type those numbers), but actually working the faces like a fun day at Rincon, I'm blown away. There is a dedication and focus in big-wave riders which is comparable to that of anyone in the world. This a great film. I gave it a 9 instead of a 10 only because it neglects to mention that there are great big-wave riders in the world outside the Hamilton/Kalama crew, and I think they deserved mention. Splice in Ken Bradshaw at outside Log Cabins and a 10 it is! Question: is it a positive review?

yes
