When one of their twin boys is stolen from them, the parents(Charanraj and Saranya) are grief-struck. The stolen child grows up in a village as Vetrivel(Surya), loved by the entire family that adopted him. The son who is still with his parents grows up to be Vasu(Surya), a private detective. Love blossoms between Vasu and Swathi(Asin), the hostess on a TV channel. One a trip to the village, Swathi spots Vetrivel and informs Vasu of his look-alike. Vasu is convinced that Vel is his brother and wants to bring him back home but Vel is unwilling to leave the family that raised him as their own.

Everything about the movie is old-fashioned. From the story about brothers separated at birth to the the long-winded dialogs spoken by Surya(he even rattles off a long dialog with rhyming sentences a la T.Rajendar at one point) to the overload of sentiments(father, mother, brother, sister, uncle, aunt... if there's a relationship not touched by sentiments in this film, I can't remember it), the movie is an unabashed throwback to the 80s.

Vel marks the first time Surya and Asin have been paired together after Ghajini. But viewers looking for a repeat of the lovely romance from that film will be sorely disappointed. The romance here is shockingly chauvinistic(the take-off for the romance is when Surya rates her 'suitability' for marriage after comparing her to her friend and at another point, she says that a wife should give up her dreams and support her husband after marriage!) and under-developed and the couple exhibits little chemistry. There are a couple of situations(which still could've been exploited better) that get some smiles and some amends are made for the blatant chauvinism, but for the most part, the romance is weak and silly.

Whatever the complaints against Hari, one thing he can't be blamed for is crafting a slow film. He has always managed to deliver screenplays that keep moving forward without giving us time to think too deeply about the goings-on. That's what saves Vel too. Though the movie is about twins separated at birth, one of the oldest plot points in Tamil cinema, the story doesn't always proceed in the way we expect it to. Plot points that we expect will be dragged on(like the twins knowing about the existence of the other) are presented earlier than expected and plot developments, atleast upto a certain point, aren't always predictable.

Movies with heroes in dual roles usually have fun by presenting different characteristics in the two roles. It makes the movie interesting for the viewers and the actors welcome it since it gives them a chance to play different characters in the same movie. This was the tack followed in movies like Amaidhi Padai, Vaalee and Azhagiya Thamizh Magan. But there is no difference between the 2 characters played by Surya here. Both of them are good, fearless and honest - in other words, typical Tamil cinema heroes. So the usual plot point of making them switch places does nothing much here. There is not a lot at stake if their real identities are revealed and so the usual fun, excitement and suspense arising out of their mistaken identities is completely absent.

After all the hullabaloo about separated twins and mistaken identities, the movie comes down to the fight between Surya and Kalabhavan Mani. Hari goes into Saamy mode here as Surya relies on brain and not just brawn to bring him down. A couple of his techniques are good and its nice the way the professions of both Surya and Asin are used in his game.

Surya has no trouble playing the hero in this commercial outing. He has developed enough screen presence to carry off the aruvaal-brandishing hero role and delivers his threats with the forcefulness required. Asin looks cute as always but is barely seen in the second half and has only one scene of any importance. 'Kalabhavan' Mani is loud but rather ineffective as the villain. Vadivelu has a comedy track that, following the recend trend in his comedy tracks, mostly involves him getting hurt in imaginative ways.
