Kidnap is the story of a guy kidnapping an industralists daughter and the clue-hunt that ensues after. The story is skewed. The basis of the story is in the exaggeration of small incidents. They look unbelivable, and hence it cant hold attention. There are some small (action) sequences which you may like, but nothing more. 

Acting wise, sanjay dutt was the only saving grace. Imran Khan has no expression, and no dialogue delivery; minissha , and vidya are equally pathetic.

Songs are too bad, and without context.

This is standard sanjay dutt forumala film - some dialogues, some action , some style, and plenty of skin show by minissha.

Showbiz is the story of media, journalists, and how media convolutes or rather constructs the story. This interplay is showcased with an interesting tale of 2 media barons, few journalists - both good and bad - and a celeb singer and his (lady) manager. of course there is love affair between them, and a fallout and then reapproachment between them.  Basic story is interesting ..

But then here ends the good part - there is (unneccessary & )ample amount of bollywoodish masala - love affair, unneccessary stoic silences ,breakups .. The film doesnt have depth. Many things too fast for the sake of moving the story. At the same time hero waits till the end to clear up some parts of his life - looks artificial .. 

Acting wise - its okay. but nothing compared to somewhat good levels which we see in bollywood nowadays. 

even though this  is a bhat camp movie, the MUSIC SUCKS !!

My advice - dont watch it. There were just 10 people in the cinema when I watched it ! It is a 1.5 starrer.
