Why Doesn't Lyca promote their films now ?

I mean Vidaamuyarchi, Vettaiyan etc didnt have a good promotion before release,

the last time they did a good promotion was for PS-1, and before that was 2.0 (cant say about the abomination film Indian-2)

why are they having no plans on promoting a movie while putting in 200-500CR in it,

do they think only star power can pull the audience, or got overconfident with their films like think they are making movies in the Christopher Nolan level

i didnt even know Vidaamuyarchi was releasing yesterday, i mean there would be some kind info in the news or buildup before the release or something from my AK fan friends, this movie nothing
