An Investigation demands detection, analysis, observation , thought process, innovative and effective ideas more over some smart and intelligent officers who can do that job without any disput. But presently, any creative team, whatever the show is, can't make that possible. Lack of ideas, Lack of knowledge even lack of experience do matter in that case. They only believe in show off things like aggression, rude behavior etc etc. That's why old investigation shows still attract us even now. That's why Sherlock Holmes never made again. That's why CID never went back to its top.
When we see shows like these now, its very much predictable about each scene, each move. They can not create that magic work , which will bind us with the show. Now-a-days we don't even feel any type of interest to sit there and watch full show.
