Did You Know?


When Chin Ho and Danny Williams bring an assault rifle to Steve McGarrett that they report having found in the room of murdered student Kenji Tatsumo, McGarrett asks if "Che Fong" found any prints on the gun. He asks this even though Harry Endo, who played criminalist Che Fong on the show for years, had already made his final appearance in the role in the season's premiere episode, and all of the forensic scientists with whom the Five-O members interacted in the intervening episodes were women, including two named "Charlie" played by different actresses.

Rather clever.
27 November 2012 | by (Bradenton, Florida) – See all my reviews

Most folks living here in the continental US probably have no idea that Hawaii is located in a precarious place in the Pacific and it has, on occasion, been hit by massive tsunamis--such as 1946 and 1960. So, the plot in "Tsunami" isn't really that outside the realm of possibility.

The show begins with an ambulance being stolen and one of the crew being run over by the thieves. This causes one of the perpetrators to think twice about their plans--he wants no part of a heist that involves killing or nearly killing anyone. However, as you'd expect on the show, he's soon killed by a very rabid member of the gang. As for the gang, they are an odd group. They are NOT professional criminals but some amoral but very bright university students--so full of themselves and their supposed high IQs that they think they can out-think Five-O. Their plan is to fake a tsunami warning and use this as a cover for a jewel robbery. The plan is very clever but, of course, not clever enough.

The biggest plus of this show is novelty. While one early episode did talk about tsunamis in Hawaii, "Tsunami" was still very original and the plan quite involving. The only part that seemed silly to me involved a scientist whose glasses were smashed. You'd still think that he'd have SOME indication of what his captors looked like even if he had severe vision problems. Heck, he couldn't even tell the police their hair color, race or anything other than that they sounded 'young'. Still, this is a very minor problem in an otherwise involving episode.
