hmm - IR actually sounded like he was being positive about Mysskin's compliments!! ".. avara manasula yenna odikkitturukkoongaradhu yenakku theriyum..andha vibrations yennakku theriyum..pakkathhula vara vendaam..aanaaa, yenakku ella iyakkunargalukkum recommend panneengaley, yenakku oru mediator vandhadhu neenga orey oru aal thaan...." and then there is a pause, looks like some part was edited before he says "...yenakku yaarum thevai illai (repeats it again)..yenendraal, iraivan yennai andha idathhil vaithhirukkiraar...nee kidadaa naaye yendru vittaar (only at this point, I see a hint of anger perhaps ?)..andha saptha swarathhileyey kidakkiraen..angeye kidappaen..angirundhu veliyey vara maattaen.."
The other place where he mentions about Mysskin packing off after Nandalala comes right after his reference to doing 2 extra songs besides the five required for the film, which the director COULD NOT refuse from using! which is in context with what Mysskin did with his songs for Nandalala (not using 2 of them in the film) that must have irked IR and also the fact that he has confirmed ARR in his next film and onstage sounds like he is 'personally recommending IR to new directors' as a means of compensating his 'nazhuval' from IR post-Nandalala!!
In such an overall context, Mysskin should not have said things the way he did - given IR's complex personality and his supreme self-respect
