The narrative lacks interesting ascent sequences and moves slowly. 'Thangalaan' is a mediocre film, even with the outstanding performances of the main characters. The film is mediocre because of its dull first half and its complicated second half. One significant flaw in Ranjith's usage of sync sound is that it makes it difficult to follow their accent and interpret their feelings.
The film's overall effect is weakened by the convoluted political themes and mythological tales. Given the considerable production value of the movie, the visual effects are cheap and unimpressive.

There are some brilliant stretches in the film, but such moments are sporadic and not consistently present throughout the film.
