This CSI show is so awful that it is difficult to make a short list of what is wrong with it. First of all, there is no "CSI" in the show, even though it is named CSI: Cyber. They aren't doing crime scene investigation. They are doing evidence forensics on technology recovered by actual CSI people. But they show them visiting crime scenes and doing other activities that a forensic specialist would never do. I guess this isn't any worse than the instant DNA tests and one day court cases we see on other shows, but who needs inaccurate methods on a show about methods?
It is clear that they have no technical advisers, or if they do, they are incompetent. There are errors that exist that have no reason to exist. Sometimes you have to take shortcuts to make a plot work or something, but they insert ridiculous dialog and ideas when they don't have any reason to do so.
This show really isn't any worse or better than the Scorpion show, which for some reason puts the name of itself in a close tag. When the show's title is an error in itself, how much can you hope for?
