I also did like how they tried to mixed the romantic side  with some action, and we all like to be surprised, as at the end when Jenn´s father is the one that was trying to kill his husband, no one was expecting that, a very nice plot twist.

Yet the great effort and good elements they had :actors, main story and plot twist, for my point on view the directors didn't brought together well all those goods elements , it was just too much and way too fast, they cut out so much, a esential part of a romantic comedy is how the relationship develops and they just went from 2 dates to get married, they should have show more about them and the beginning of their relationship. 

Also as I said before I like when movies have comedy and action but this was just another wrong attempt of that , The plot is like a rip off of Knight and Day & Mr. and Mrs. Smith but with less action and more bad jokes.
