Why do Vishal's cop movies fail?

Vishal has the look, physicality, screen presence, and the action skills to pull off cop roles but all his cop movies were duds.

I'm yet to see Laththi, which had a great teaser, but the movie was never talked about after release.

Irumbu Thirai and Action don't count since he wasn't a cop but military in those.
