These are all from like 2005-2010 (I was younger and forced to go see Bollywood movies with my parents all the time). Not all of them are all-time greats per se (though some are), but all are very solid movies at the very least. 3 Idiots MBBS Munna Bhai Om Shanti Om Don/Don 2 Dhoom*/Dhoom 2/Dhoom 3 (Dhoom 2 was kind of a weak link) Bunty aur Babli Rang de Basanti Chak De! India Jab We Met Dostana My Name is Khan Udaan** *Dhoom is the only movie on this list with bad reviews (2 and 3 have great reviews) but I loved it. Frankly, I liked it more than Dhoom 2. **I haven't seen Udaan but its reviews online + from friends/family are good.
Airlift - true story about how one guy helped thousands of Indians escape Kuwait during Saddam Hussein's invasion Ship of Thesues - havent watched this yet - it isnt a regular 'masala' musical movie. But it has some really good reviews Udta Punjab - fictional movie about the drug problem that is affecting the state of Punjab through the view of policeman, doctors, poor....(it's not like the movie Traffic)
