Although it has its amusing moments, in eneral the plot does not convince.

I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

The film creates a perfect balance between action and depth of basic needs, in the midst of an infertile atmosphere.

Story: It's very simple but honestly that is fine.

I saw this movie in theater because I like Madhvan. and my expectation did not go waste either . This movie is one of the few good horror cum thriller from Bollywood . Movie keeps you involved from start till the end . There is enough explanation for every incident happening in the movie .The movie does not gives you a chance to call it as bogus. In spite of made in low budget , movie keeps you tied to the seat .End is not at all predictable like in most of the movies . All the actors have done a good job .For some movies , its the acting and for some movies ,its direction , for some ,its humor , for this movie ,its the story that makes it worth to watch .

Good and unique scenario, but not unaccustomed to Indian acting. On the whole, 13B is interesting in parts, not in entirety. Also, as mentioned earlier, films of this genre, the world over, have a shorter duration [1.30 hours or 1.45 hours] and the approx. 2.28 hours' running time would test the patience of the viewer. At the box-office, with cricket matches on one hand and examinations on the other proving major oppositions, this scary movie would prove to be a scary proposition for its investors. The problem is, 13B takes its own sweet time to come to the point. Besides, you can't help notice the blemishes in the screenplay. What eventually comes across is a film that had the stamina to win the marathon, but which runs out of breath and starts huffing and puffing midway. If you have time, I recommend you to watch this movie. Just be patient!!!

This is a very good thriller and must watch one for cold blooded thriller fans. P.C.Sriram plays a vital role in the movie. His camera work is extraordinary frankly to say he deserve Oscar for Cinematography for this film.I can't believe it is Vikram K Kumar's First Film.His Directing style is very good.Maddy did a nice job and all other actors also did a good job.If you want to Feel the Fear means watch it in Theater don't watch in CD's. First of all thanks to the production team for giving us such a different thriller in Tamil.Little mistakes are there but i won't mention it because your work is really fantastic. A Must Watch Thriller Film with FAMILY.

A great horror thriller movie in Tamil after a long long time.... An awesome script executed to near perfection. The cinematography by PC Sreeram is world class. The background music by the first timers is absolutely outstanding and complements a brilliant script beautifully. I was completely overwhelmed by the movie when i saw it the first time.. Twist after twist in the second half leaves you no time to think and is absolutely breathtaking... Acting by Madhavan is again brilliant.. Editing by Sreekar Prasad definitely needs a special mention. A duet song could have been avoided... The acting by the person who comes as the police inspector is first rate and provides comic relief at certain places. This movie can challenge any Hollywood movie... Kudos to Director and Madhavan for making such a wonderful movie. 2009 is yours.
