Ra.One tops followed by ETT and then Ghajini..there is only one true opinion for it and that's this, no other opinion can be true..Ra.One had humongous buzz, unachievable for any current movie, though TZH can replace ETT.
Secondly if Srk ft. in the Tubelight trailer or promos then it can touch the level of Ra.One's buzz considering Srk-Salman together hype..
Btw Dangal buzz is well below movies like Krrish 3, HNY, Chennai Express etc... Dabangg, CE, Bodyguard deserves place on top 10...
My list would be
5. 3 Idiots
7. Dhoom 3
8. Happy New Year
9. Chennai Express
