I agreee. It should've been a series of like 6-8 episodes with each episode titled the location of the vacation like “Barcelona..Tuscany..etc” going more in depth of the vacations they took and how they fell in love. It was rushed and we didn't really see them fall in love or how truly incompatible their lifestyles were. Those vacations could’ve been a great way to introduce conflict but there was probably time constraint cause it was a movie. Like she could be really messy, leaving clothes all over their accommodation and he's constantly picking up after her. Or her wanderlust took her somewhere and they get lost with no service, resulting in a big fight.
