I'm a very big fan of Dick Van you-know-what, from way back -- really, I am. But I really detest "Diagnosis: Murder", from my admittedly minimal exposure to it. TV for complete dummies.
I once had the misfortune to catch the "Dx: Murder" ripoff of "Now You See Him", which stole the same idea of the kller being a magician who supposedly was inside a tank of water, on stage, throughout the murder. Here is one of the many differences between the 2 shows:
"Now You See Him" at least established that, while the magician is supposedly marinating in the water-tank, the audience is entertained by his daughter, prancing about in a skimpy costume doing sleight-of-hand tricks.
But in the Dick Van you-know-what version, we are asked to believe that the audience just stares at a still tank of water for about 15 minutes, while the killer is off doing the murder. What audience would put up with that abuse of their patience?
How stupid and unbelievable can it get. Stupid, stupid, stupid.
