First of all who is comparing any of the films here? It is the compilation of cop films.
A cop film is something with a cop's story narrated. The lead character being a cop. The whole narrative is aided by the character.
So your issue is only with Talaash & not with Monsoon Shootout or Shagird? Monsoon Shootout was more of a neo-noir.
Like I said, this is not comparing. And Talaash is one of the many films that handled PTSD. Not at all rare..
And a cop film doesn't mean action film. Cop film can't be a drama? Or a thriller? Phata Poster Nikla Hero is over the top comedy film. Not till the end, Shahid becomes an actual cop. Shouldn't it be named here?
Talaash is every bit of a cop film as others on the list.
