"Bomb, Bomb, Who's Got the Bomb?" If the juvenile-sounding main title is any indication, then I should've figured out right from the get-go that this episode was gonna test the old Five-O credibility rating. And it did.
The premise that Senator Henderson has a totally split personality is a bit hard to accept. Not that such a case isn't clinically possible, but hasn't anybody on Capitol Hill ever noticed anything strange about ol' Harlan before? No? Even though his condition is severe enough that he runs around hiding bombs? If I were in Washington, I'd be afraid to hit the men's room.
How about the fact that one side of him doesn't know what the other is doing? The likelihood of all this as it unfolds in this episode strikes me as--well, unlikely. If he's gotten to the point where he's blowing things up, don't you think his "other half" might notice some evidence of this lying around the house somewhere? Like, a couple of his own fingers, or worse yet the maid, or perhaps a burned-out room or two in the east wing?
Oh well. Marc Singer portrays Randy, the youthful son-in-law who's at odds with the Senator. During the '70s, Marc Singer spent a lot of time playing the sympathetic young man (see episode #172, Target--The Lady, opposite Susan Dey, as well as many similar roles in other TV programs) who seems to be trying hard to debunk the stereotype of youth in those days--hair cropped short, no beads or peace signs, not a trace of a tatter or a shred of irresponsibility. Anyhow, he's here with wife Melody Patterson (Danno's real-life wife at the time--wonder if he was jealous?), showing nothing but cooperation and sincerity. Displaying such obvious believability, and because he's our first suspect and most obvious suspect, and because it's only Chin and Ben (not Steve) who are giving him a hard time during questioning, you KNOW he's got to be innocent. Yep, he is.
Now, when the Senator tries to commit suicide (!) by blowing up his own secretary, (?) stock 5-0 actor Beau Van Den Ecker is watching the estate and burns rubber hauling it out of there. Why? If, as it is explained, he's only there to get some dirt on the Senator and his committee, then wouldn't he just sneak away quietly? I mean, if you're an experienced crook and you're leaving in order to dissociate yourself with the explosion 'cause you've got a rap sheet a mile long, would you really make like Mario Andretti with your Lincoln?
Moving along...why in heck does the Senator's elevator at the Ilikai stop halfway up? This isn't made clear to the audience, but I suspect that the real reason is, ahem, so McGarrett can save the day from the top of the elevator car thirty stories up. Well, to make a long story longer, the reason why the Senator suddenly identifies McGarrett as his long-dead father is also unclear. Are such hallucinations symptomatic of, and consistent with, schizophrenia? Is this lawman who pops out of the ceiling supposed to be the dad because he's established himself as an authoritative person? Isn't the Senator then mixing reality (knowledge that McGarrett's a cop) with delusion (thinking that he's daddy)? Isn't this a bit contrived?...
Oh well. I like the way McGarrett solves the crime--disregards everything his detectives say and instead bases his conclusions on the findings of an Asian handwriting expert who talks in riddles; and on 5-0's consulting psychiatrist who, without ever meeting with the Senator, decides that this must be yet another case of multiple personality disorder, ostensibly because she's got her own patient that she's treating for this malady (the whole town is crawling with 'em, Steve-o), albeit this patient is of different background, sex and age....
Oh well. At least we can fall back on the fact that our fearless crime-fighting hero will do whatever it takes to save the day, right? Nope. It is so obvious that it's a stuntman (John Boley Nordlum?) on top of the elevator that one has to wonder why the director didn't either use a longer lens, or at least try to make the stuntman's hair look a little more like the famous McGarrett coif. Oh well.
P.S.: William Windom, who plays the Senator, portrayed the prosecuting lawyer opposite Gregory Peck's memorable Atticus Finch character in the famous 1962 movie "To Kill A Mockingbird". I think he does better with characters that are limited to just one personality. Oh well. Despite all this, it was a pretty good episode.
