It's about as good as I thought it'd be, which is to say, not at all. Amrish Puri doesn't so much chew the scenery as he swallows it whole. This movie's so full of overacting that it makes Shah Rukh Khan's performance look restrained. There are ridiculous fistfights that are so poorly choreographed that you can see the hits missing their targets over and over again. There's an unnecessary secondary romance subplot that is just an excuse for eye candy. There's the complete lack of any sort of logic in the reincarnation plotline. I know, it's a story for those who have faith, as it says during the opening scenes. But can't faith and a little good plotting go together? Apparently, not here.
Shah Rukh and Kajol are hot together. And she looks absolutely gorgeous, a very different avatar from her NRI-next-door look in DDLJ, which came out the same year. But that's the only good thing about the movie.
Here, for your viewing pleasure, I present the abbreviated YouTube version of Karan Arjun. I watched it so you don't have to!
This is Karan (Salman Khan) and Arjun (Shah Rukh Khan), two brothers living with their mom in a random village. Their dad abandoned them years ago but they take good care of Maa (Rakhee):
Saxena is pissed.
And before you know it:
At the engagement party:
Saxena gets Ajay to fight Vijay:
But when Saxena tries to blow Vijay away with a hunting rifle, Ajay tackles the older man and screams:
He does, and Ajay gets taken to jail. After he leaves, Amrish Puri, proving to be an even more excellent father-in-law than he was father in DDLJ, tells Sonia:
Very picturesque. So he takes them up to his ill-gotten mansion so she can be forced to wed his son there. Of course, Vijay and Johnny Lever come running after, but not before agonizing over the illogic that is Vijay's life:
They go on a rampage and kill everyone, including the Big Bad Guy, whose death is clearly implied to be a sacrifice to Kali. Then the garlanding.
