Apart from the different roles of the female character ( an environmentalist lawyer) there is no difference in the movie two weeks notice and other movies which may fall under the category of romantic comedies.
it also has a casanova rich dude. who has a different side which no one sees. he acts dumb in front of the girl and consults her on every teenie weenie matter like color of his shirt.
the only good thing about the movie was it is based on something we shud all be be pretty aware and conscious of environment protection and heritage preservation.
being a bombaywaala, I feel heritage is something we have been handed over by our ancestors. it is very evident from the attitudes of young people how we are not trying to keep what we originally have and are trying to make new things.
let the old live on as the new comes along.
the movie subtly gives out ths msg which gets lost in between all the mushy and funny conversations.
