Raj (Indrajit) has the ideal life - a very high-paying job, a hot wife Pooja (Manjula), a cute daughter Ammu and an even cuter infant son. Just when you think he has the perfect family, it suddenly doubles in size - Kavya (Charmme) joins it.
Pooja first runs into Kavya when Kavya dives to save Pooja's daughter from coming under a lorry. Pooja feels guilty since it was because of trying to save her daughter that Kavya incurs an injury, but Kavya tells her that it's okay since she would have sustained the injury even if she had dived in front of the lorry just like that. Okay, she perhaps doesn't actually say that, but if you are looking for logical cohesion in this film, it's going to be a long day.
Discovering that Kavya is unemployed, Pooja does just what anyone in her position would do for Kavya - she tells her to eat much lesser. Okay, she doesn't, but should have, anyway. What she does is give Kavya a job in her house as a nanny for her kids. Kavya starts to enjoy herself in this role, everyone is happy, and you're thinking that this must be the ending of the movie and luckily there was no script, when suddenly the ghost appears. Well, almost - it is actually just Ravi (Shashank), Raj's brother, but he is more painful both to Kavya and the audiences than any ghost could ever have been.
He keeps chasing Kavya promising her that he'll love her till he dies, and fortunately for everyone, he dies - a mysterious car accident takes care of him. Just as Raj and Pooja start to come to terms with this, other weird things keep happening that slowly crank up the tension - random objects disappear, a docile gardener suddenly appears lecherous, the couple start to suspect each other, Pooja gets hospitalized, and finally, a close friend of the couple dies a gruesome death.
Indeed, there are times when a sequence of intriguing events makes a movie which appeared like a lost case until then, suddenly get the adrenaline flowing in you, gripping you to the screen to avoid missing even one scene, and forgetting even the popcorn as the leg-grabbing frenzy unexpectedly takes you over. Unfortunately, this isn't one of those movies. As you beat a strong sense of dÃ©jÃ vu from your Fatal Attraction and Poison Ivy memories, it is all you can do to watch politely on as the scenes unfold predictably.
Kavya's Diary ambles on through its first half, getting so boring within an hour that you want to gently whisper sweet nothings into the ear of the person sitting in the front row. It also takes itself too seriously - it has songs and all, forgetting that it is a low-budget film with no stars who can make the audiences forget that there's no script happening in the background. Charmme is the only face known to the audiences, and the makers of this one seem to think that's a plus.
The movie kind of picks up in the second half, depending on your definitions of "picks up", "second half", and "kind of" - in any case, a movie outing where you get to see a psychopathic killer on the loose, innocent people scared for their lives and sirens blaring as cops descend in dozens, is usually exciting, especially if all that is happening on the screen.
Manjula and Indrajit lend grace to their characters, too, especially the former. Charmme cannot bring the intensity her character needs, which is a significant reason that the film falls flat on its face. The character of Shashank is a complete pain. And the script has more logical loopholes than your colony has power cuts each day.
Like we said, the movie has songs and all, which create an awkward silence between you and the others you came to watch the movie with. Actually, there'll most probably be an awkward silence anyway - and for a while.
