It's been said before by better directors and writers
Full Review:
The 'what if'/'if only I had known' genre is not served by this badly-written, badly-directed 92 minutes of my life that I will never get back.
Catherine O'Hara and Joey Pants are splendid as always, but there are too many characters given equal importance, leading to a choppy and unresolved story.
For the best of the genre, check out 'Memento' and 'American Beauty' instead.
