You guessed it right, Slumdog definitely features in my list. As a person who has seen every Oscar winning "Best Picture" movie since 1929, my least favorites are below
Not in any particular order, though Rocky would be the last.
1.Rocky
2.Crash
3.Gandhi
4.SlumdogMillionaire
5.AmericanBeauty
I would rate the above movies between mediocre to very average but definitely not Oscar material. Very happy that ARR won 2 Oscars, however even getting a nomination for Best Picture category was quite a shocker to me. Hope 82nd one turns out to be a pure performance show rather than driven by any external factors.
Anything.....for a friend
