I can say there was nothing right with Vetaikaran. There is a big list to say sucking things; 

• The movie looks like Telegu movies of the 90’s.
• Heroin is added just for the heck of it.
• Scenes are too dramatic.
• No continuity.
• Villians getup looks funny and they end up being comedians.
• Vijay using alcohol and lighter to kill a Villan peaks the comedy.
• Heroism beyond acceptance.
• Costumes & Hero’s getup takes back to late 80’s Ramarajan times.
• Comedy scenes end up as pain in the neck. Hero & serious scenes fills the Gap left by comedians. 

We can add more to the list but I don’t want to take that much pain to recollect the entire movie and put myself in to a bad position. 

In spite of all these minuses there is couple of positives like;

• Anuksha Shetty.
• Vijay Antony’s music.
