It's a jolly holiday with Rani.

 Thoda Pyaar Thoda Magic (2008) opens with a montage of tragedies befalling young Ranbeer Talwar (Yash Belani).  His only friend moves away, his mother dies, he's sent to a boarding school, and the only teacher who bothers to build a connection with the intensely lonely boy is transferred away.  It's an Ebenezer Scrooge origin story, and sure enough the adult Ranbeer (Saif Ali Khan) is driven, competitive, cynical, and more than a little misanthropic.  After winning a major business award, he takes the trophy and stalks off without a word.  On the drive home he looks at his phone for a moment and runs into another car, killing a young couple.  Ranbeer is horrified, and quietly waits for the police.

A year later, Ranbeer arrives at the courthouse for his sentencing, with his self-centered socialite girlfriend Malaika (Ameesha Patel) in tow.  The judge (Sharat Saxena) reminds the courtroom that the real victims of the case are the couple's four orphaned children, and sentences Ranbeer to parenthood; he has to give the children a home and take proper care of them, and if at the end of a month the children have any complaints against him then he'll be sent to prison for twenty years.  This seems needlessly cruel to both Ranbeer and the children, and it would be kinder just to send him straight to prison, but that is the premise of the movie.

And then the movie introduces the kids: responsible but angry older brother Vashisht, level-headed and tough sister Aditi (Shriya Sharma), adopted brother and Sikh Iqbal (Rachit Sidana), and adorable little sister Avantika (Ayushi Burman).  There's also a dog, because the kids are loosely modeled on Enid Blyton's Famous Five.  (Young Ranbeer's teacher gives him a copy of Five Go Off in a Caravan during the opening montage, which is kind of a tell.)  The kids are not okay; they are sad and angry and determined to stay together, driving all of their well-meaning adult relatives away with a series of pranks.  This is their chance to punish Ranbeer, and they intend to take it.

The first day goes really badly for everyone, and things don't improve.  Soon everyone is praying for help.  Fortunately, God is played by Rishi Kapoor in jocular and avuncular mode, and He sends help in the form of Geeta (Rani Mukherji), the naughtiest angel in heaven, who takes a job as the nanny for the family, because this is actually Bollywood Mary Poppins.

I say Mary Poppins, but it's really Bollywood Nanny McPhee, mixed with a bit of the police drama/family film One 2 Ka 4.  The children try to drive Geeta away with pranks, all of which backfire because she's secretly an angel. She wins them over by taking their side against Ranbeer, but she also encourages Ranbeer to think about things from the children's perspective.  

There are magical shenanigans, including a birthday trip to the museum which turns into an adventure through time and space (including a battle on the India-Pakistan border, because clearly these children have not been traumatized enough) and things start to get better.  One by one the children start to see Ranbeer as a flawed man who made a horrible mistake and is trying his best to make amends, rather than as a monster.  Malaika leaves after her sexy dance number during her birthday party is spoiled by tiny CGI sea animals, explaining to Ranbeer that she just can't handle the kids.  Ranbeer stands up for the kids during a business trip to Los Angeles, and they all realize that they have become a family.  This means that Geeta's work is done, and it's time to return to Heaven.

But you can't build a family from the outside.  The children have grown to love Geeta, and she's grown to love them as well.  And because this is Bollywood, Ranbeer has fallen for her; he makes his best pitch in the form of a song, and Geeta is overwhelmed and runs away.  The new family goes to look for her, and wind up in a church, asking God for one last miracle.

This is kind of a weird movie.  Tone is an issue, as the film switches from trauma to wacky pranks to magical hijinks to heartwarming family drama at the drop of a Handbag of Holding.  Malaika's dance number is surprisingly spicy for a children's movie, and I would say that the movie's metaphysics are lifted from The Good Place, except that the show came out eight years later.  (Still, Jeremy Bearimy.)  And it seems like the entire special effects budget is blown on Geeta's introductory song.

Despite all that, though, I can't help but love the movie, and that's largely due to the cast.  Saif Ali Khan dances neatly between comedy and drama, Rani is always delightful, and even the child actors are good, particularly Akshat Chopra as Vashisht, who manages to pack a lot of rage into a sunny children's fantasy.
