I agree with this wholeheartedly; in fact I just went on his page to express how amazing a host he is.
I've watched him in MKMM and in JD, and he's been superb in both. He has a great sense of humour and cominc timing, and a fantastic personality to match. His on-screen presence and charming good looks are just an added bonus!
I think it's more than safe to say that JD would not have been the same without Ayushmann.!
