What if your side profile looked like Hrithik Roshan? And you had Priyanka Chopra as your alleged girlfriend? And you had a producer father making a sci-fi movie with never seen before effects for your debut? Life should be pretty good huh? But for poor Harman Baweja it goes all awry.
So the movie opens with Karan’s(Harman Baweja) entry(we have to see bits of him from his fingers to his glasses to finally see him in full view 
) desperate to get his dad’s attention. You see Karan is stinking rich but has no one love him…his dad is too busy and his mom is dead.
So our poor little rich boy does loads of dare devil stuff as no one’s gonna miss him if he’s a goner.
Till he runs into a giggly Sana(Priyanka Chopra) who loves painting n poetry(at least what she calls poetry) and writes in her diary daily n actually says stuff like Dear Diary(such characters do not appear even in Mills n Boons these days) and soon he has someone to miss him
All is going good for the lovey dovey pair till Sana gets killed off in an accident just before she can give Karan a kiss with her cold cold lips after a strawberry ice cream. 
Poor Karan is down in the dumps. But he does have a wacky scientist uncle, Uncle Ya who quit NASA to work on his time machine. After 15 years he does get it to work just in time for Karan to get to Mumbai 2050 where he’s sure he’ll find Sana again(the things men will do for a kiss ).
So Karan, Uncle Ya(Boman Irani) and Sana’s siblings land in futuristic Mumbai where they do discover Sana, only now she is Zaiyesha, a pop star who hates poetry and loves death defying games but still writes Dear Diary stuff!!!.
They also help fix a robot who insists on calling Karan sexy (someone should shoot that Balaki..the Cheeni Kum director) and agrees to help them get Karan woo Zaiyesha back.
Oh and he has to do this in 30 days or the time machine will return without him and he’ll age 50 years overnight 
So Karan sets about getting Zaiyesha to flip for him and he also battles an evil dude(who looks like Darth Vader n his entire setup comes from Star Trek..did you get the props at a discount Mr Baweja????) and makes it back to 2008 in the nick of time with the love of his life(shouldn’t Zaiyesha now grow younger by 50 years?? N the robots not function???)
You wanna make a movie called Love Story you first write a good love story…not inane stuff that’ll make you wanna smother the lovers.
And if you want make a sci-fi movie with never seen before effects then come up with something that people didn’t see years ago in Back to the Future 
And anything that borrows from Star Trek sucks….law of sci-fi.
Kareena Kapoor had brains walking out of this one(though she did do Tashan after tat ).
Priyanka Chopra disappoints in this one..can’t blame her much though, both Sana and Zaiyesha are dicey characters.
And Boman Irani!!!!! Wats up with you? How can you do an inane role like this one?????
And finally Harman Baweja. He doesn’t look too much like Hrithik or sound like him. And he definitely doesn’t have his talent. Maybe if he stopped trying so hard to be Hrithik(he even tries to deliver his lines in a similar fashion!!) he might find a place of his own(rem AB Baby? He did so much better once he stopped trying to be Pa)
Love Story 2050 manages to disappoint all on it’s own and wow it needed absolutely no help from Aamir Khan’s alleged “lets ruin Harman” campaign.
Stay away. Even if you are 5 and like pink teddy bears.
