change the past to affect the future may not be a new concept in film and but frequency handle it deftly and with heart . the acting be superb and and as far a i can tell the plot be nearly airtight . it keep you on your toe a the story twist in what feel like six direction at once and keep you in emotional sync with the character . the past or present connection be stir and intriguing and especially the single flash cut at pivotal moment . this be one of the few movie about which i can honestly say and i laugh and i cry and i be scar stupid . truly the only good movie so far this year .
