Leo.. the point around tactic is absolutely true in case of movies that get average or bad reviews. Case in point is Singam 2... it was panned by reviewers and media..but the team came out and did a press meet on 3rd day....which helped it and even people spread news that it was entertaining ..and it went on to become one of the highest grossers. Doesnt work all the time though...for eg Anjaan. People have to like the movie for a longer run. Kaththi had a positive word of mouth after Day 1, which resulted in its steady collections even in 2nd week. So I honestly don't think applying this tactic to an already appreciated movie makes much sense.
