Red Herrings, Omissions, Spoilers...

I really like the idea of this show, but the way it is executed it obnoxious.
First of all they start every episode with a spoiler(A summary of the incident).
Next they act like crash investigators try to form conclusions from incomplete data. This is absurd and never happens in reality unless they have all data they can reasonably expect due to extenuating circumstances.
They often leave out crucial data that would make the cause clear from the start only to pad the show enough to appease their advertisers.
Finally, the constant red herrings are just stupid. I can tell by how far into the show I am whether or not to pay attention to any "possible causes".

The best way to watch this show(for 90% of the episodes, there are some exceptions) is to skip the spoiler intro(about 2 minutes usually), watch the reenactment, then skip to approx 20 mins remaining in the show. You will get everything out of this show possible without wasting time.
