karan johar have do it again . this movie be absolutely wonderful . it have it all comedy and romance and and deep emotion . you have be warn represent this be a tearjerker . don not bother watch it if you hate sensitive film . shahrukh and of course and be the show stealer . nobody can ever replace this brilliant star who can transform perfectly into his character . saif and the underestimated star and be great with comic timing a he be in dil chahta hai and na tum jaano na hum and etc . preity zinta be good but wasn not as great a she be in koi mil gaya . jaya have a nice role . song be excellent and and in my opinion and the best soundtrack of the year . the portion of 6 din and ladki in in the second half be a bit of a drag and however . the best part of this movie and though and be it theme . carpe diem . people be so concerned with their future that they forget to live the present . god only know where we will be tomorrow . enjoy today before it too late .
