Okay, I understand that some "artistic license" should be allowed. Real life is MUCH more exciting than any show but portraying it on television from all personal angles that make it interesting is impossible. That's why we ALWAYS have some sort of a "crutch" to get the show moving to the next phase. But... NOT LIKE THAT!!!
First, a young man calls his mentor and says, "I found the clue to your mystery". OF COURSE the mentor's phone which worked even through a sniper shooting onboard his yacht SUDDENLY loses all its charge. Okay, fine, this cliché has been used in hundreds of shows. It's stupid and unimaginative, but... FINE, have it. But THEN the season dives into an entire pool of clichés. SUDDENLY the notorious criminal who died in a fire is not dead. Nobody believes the pathologist, even though everyone believed his every word RIGHT until that very moment. The drug the young man was poisoned with is SUDDENLY known to enhance brain performance, and OF COURSE the medical student simply overdosed on it. The pathologist in question receives threatening phone calls but police refuses to investigate because... yep, the guy who called "is dead".
I've never in my life seen a whole season based entirely on dead beat clichés. Usually the writers lose the grip somewhere around the end of Season 3. This time, they never really got it in the first place, but the brilliant cast managed to pull the show out of the North Queensland swamp. This show URGENTLY needs a new team of writers.
BS-du-jour: The good pathologist says he received threats on the phone. His car gets burned. People around him drop like flies under more than suspicious circumstances. But even his friends in the police don't believe him because the person who (they think) shot him is dead and think he is shocked by the shooting itself. Riiight.
