First of all, a big thanks to the director for taking forward a subject in a slightly different perspective. Meagamann deals with drugs, police, undercover agent, faith, lose - all these has already been done and dusted in cinema. But this is actually a very good scripted movie which uses all these elements to its advantage. It is, though, let down a bit by its execution.
Pros: Arya is very much suitable for this role. He did justice to the role.
Screenplay is another plus as it grips the audience by throwing in something to hang on.
Dialogues - unlike traditional commercial movies, no unwanted lengthy dialogs are placed. Appreciable one.
Movie length is a big plus as it makes it more crispy.
Can be made better:
Hansika's role is almost unwanted and she is wasted in the movie.
Unwanted scenes that are targeted to bring out laugh in us but eventually fails in second half.
Editing is very good in certain parts but it lets down in certain key places.
Character importance is not given and their background is not explained well enough for the role to sink in.
Overall - a gripping enough action entertainer that will have a surprise ending! Worth for the money. Better than many commercial masala movies.
