Here's How to Tighten Up The Film
I think my biggest issue with this film is how, from the middle to the end, it was a total repatative mess.
Everything was working exceptionally well up the point of Jacob's first visit to the UK.
At that point it turned into a mess... dating others, not dating others, back together in the UK, breaking up, back with the ex's, then getting back together, getting married, back with the exs, back together in the UK, miserable, breaking up, back to the US, back together, miserable... ughhh. I might have added a sequence or two, can't remember, it's insane though.
Here's the simple solution;
After the scene where Anna comes back to the US and has to turn around, Jacob and Anna drift apart. He dates Sam, Anna dates Simon. Anna and Jacob aren't happy apart, they have another go at it. Jacob flies to UK in the hopes of bringing Anna back. They get "married" then it falls apart like it did in the film; Jacob suspects Simon the neighbor, Anna finds the texts. Jacob goes back home. Anna is about to marry Simon but flies to America for the ending in the shower.
Basically we just chop out one of the flying to the UK and coming back to date the other girlfriend/boyfriend sequences. It's 20 minutes of the film that is not needed. If they could clean that up, it would be a lot more fluid film. It just got soooooo repetative.
