Allari Naresh's "Action 3D", which has been inspired from the first part of the "Hangover" franchise, has opened to mixed response from film critics.

"Action 3D" is about four friends - Bava (Allari Naresh), Ajay (Shaam), Purushottam (Raju Sundaram) and Shiva (Vaibhav) - who set out on a road trip to Goa for Ajay's bachelor party. The boys get drunk and when they wake up the next day, they find a tiger in the bathroom and a baby in the pram.

Even worse, their friend Ajay goes missing. Having no memory of what happened on the previous night, the friends try to pick up clues to find what had happened and also to trace Ajay.

"Action 3D" has been claimed as India's first-ever comedy 3D film. Anil Sunkara deserved praise for bringing out some never before seen effects using 3D. But a poorly written script mars the film, according to critics.

Besides the four leading actors, "Action 3D" has a big star cast including Sneha Ullal, Kamna Jethmalani, Brahmanandam, MS Narayana, Jayaprakash Reddy, Suni, Posani Krishna Murali, Neelam Upadhyaya, Ritu Barmecha and Ali. Actors Sudheep and Simbu make special appearances in the film.

Here is what the critics have to say:

Karthik Pasupulate of The Times of India says, "All the funny situations in the movie seem a little too over the top and the writing isn't very sharp either. The likes Ali, Brahmanadam, Simbu and Sudeep make special appearances without really evoking many laughs. There are a few funny moments but they are too far and few in between."

B.V.S. Prakash of Deccan Chronicle says, "First things first, producer turned-director Anil Sunkara deserves kudos for bringing the 3D format to T-town."

"However, he should have put in some hard work to unearth a refreshing plot to appropriately match up to his effort, since his wafer-thin plot of four friends going to Goa for some fun and losing their way -loosely inspired by the Hollywood film Hangover seems like a patchy effort."

Sangeetha Devi Dundoo of The Hindu says, "A poorly written script packs in a whole lot of characters. Ali, Brahmanandam and M.S. Narayana have been roped in to be part of a few annoying, supposedly laugh-inducing sequences."

Talking about the performances of lead actors, India Glitz says, "Everyone delivers a neat acting output without exception.  The average Allari Naresh fan may be disappointed a bit with his relatively understated comedy, but it is no reason to blame him.  Naresh doesn't get to do the usual slapstick comedy and it is a welcome change."

"He is matched by Raju Sundaram's brilliant comic timing.  Vaibhav is slowly making a mark for himself.  Kick Shyam leaves no impact."

Verdict: Avoidable
