Since I used this word first, I'll reply to this. Caricaturish, I think, means that imitating the person in a way that makes it seem funny. That's how it looked to me. The way he walked like Sanjay and the hunched shoulder thing, it just looked like that other comedian who imitates Sanjay doing it. He does it for express comedic effect and Ranbir did it to make it look realistic but it looked stupid. Like a cartoon. I'm sorry that I am not articulate enough to have conveyed this properly. Next time I'll do better.
