However in a terse Twitter message, he did not explicitly refer to any specific issue, although the film has courted controversy over Goods and Services Tax, with BJP claiming that there have been incorrect references to the central taxation.
"Important topic addressed..... well done!!! congratulations team#mersal' Rajinikanth said in a brief tweet.
Diwali release "Mersal" has kicked up a row with the BJP taking exception to references on GST in the movie.
BJP leaders, including Raja, a national secretary in the party, state president Tamilisai Soundarajan and Union minister Pon Radhakrishnan, have been demanding that the "incorrect" references be deleted from the big-budget flick.
The BJP had on October 20 objected to what it termed as "untruths" regarding the GST in just-released "Mersal", and wanted dialogues on the central taxation to be deleted.
Actor Vishal had earlier accused Raja of advocating piracy by watching the movie online, a charge rejected by latter.
