IYO, what movie is the best ever? It may be difficult to pick one, because there have been a lot of great movies in recent times. But IMO, I give it to 24hrs. To me that movie is mind-blowing: talk of intelligence, technology, the real timing etc. I'm even of the opinion that every security outfit in every government of the world learnt one or two things from the movie because it's quite revealing and educating.
There might be some sort of conflict in one's mind trying pick one as the best, jusy try anyway and let's know which one is your best movie. Thanks
