The horror genre is really still in its toddler stage in Indian cinema. Most horrors made, are either remakes of Hollywood films, or just rather mellow. I understand that people in India can't handle anything too horrible, and like cough syrups served with sweets, its absolutely essential that horrors need to be slow, direct and coated with sweet.
That's exactly what Pizza was, which is why we had all the unnecessary footage of the love story, that really had very little to do with the story. Pizza 2, however is a whole other story. Personally, I was hoping for it to take off with the supernatural twist its predecessor left off with, and in a way it was more to do with a supernatural theme, but I'm not too sure if it was a good one.
This is a classic example of good concept, poor execution. Perhaps the director decided he needed to go extra slow to have people keep up; in fact he went so slow, it just made the film sort of dull and boring. There were no scary moments like in the first film, and the acting was poor. I didn't connect with any of the characters or their emotions, and I feel apart from weak writing, it had more to do with the choice of actors, being specially inefficient, expressionless ones.
The one thing I did appreciate was the twist they end the film with, that I did not expect in the slightest, partly because I was on snooze towards that point. Overall, 'Pizza 2' was better that its predecessor in certain aspects, but could have been done so much better and scarier. It's worth a watch for people who don't watch a lot of the 'horror/thriller' genre, and don't know what they like. But if you didn't like the first one, the second is probably not going to be any different.
