Okay, so the protagonist (best assassin in the scene) meets his younger self who is trying to kill him. If he was you what would you do, what would you tell your younger self?? Not to do the mistakes you did, right?? But this younger self is trying to kill you, so you have to save yourself too while you preach, ha ha. While all this is happening the movie never felt over the top to me. CGI of the youngee self could have been better, but they are decent. The dialogues at the end are hilariously relatable to the introspective opinions we would have of ourself today, shall we meet our younger selves. This movie is not food for intellectuals but definitely an entertaining one, and Will Smith's performance is not his best but is good enough. It's a must watch.
