Realistic

I sometimes wonder how TV series patterns emerge? How does one show have a crazy guy take the cast hostage, and then every series does an episode with a hostage taking psycho that the lead character is somehow completely unafraid of. Then the cliche ending, the main character saves the hostage taker from some life ending situation that lead him to take hostages in the first place, yet no one feels they have to answer for the fact the psychopath took hostages and will be going to jail for his actions anyways?

I am refering to last night's episode of Lie To Me in which Dr. Cal Lightman believes Eric Matheson did not kill his wife, but was framed. Then Cal and team solve the murder, have the real killer in custody and Eric demands to see his wife's killer, inferring that he will inflict some sort of harm to a man that killed his wife over 10k and a little nookie. The team cannot let this man kill a murder, not after harboring and assisting a fugitive, no this would be too far. They instead use Eli Loker as bait, and when Eric goes to shoot Loker, Ben Reynolds of the FBI takes down Eric. Because no one saw that one coming.

If shows are going to copy each other, at least pick something more believable. Love the show, but this one was a blemish on a otherwise good story line.
