Why can't love be like...

Why can't love be like in the movies. I watch a lot of cheesy Hallmark movies and it seems like the man and the woman fall in love after only knowing each other a few days or weeks. Is it just a movie thing or can falling for someone just from talking to them and getting to know them can really happen? The guy I was interested in I have known him for months and from just hanging out and going out on dates I was starting to fall for him but I guess the sentiment wasn't the same. At least it was months instead of days or weeks although I did like him from just our first interaction with each other because he was funny and seemed to know what he wanted out of life. It would be so cool if a guy was interested in me the way I am interested in him but it looks like that only happens in movies.
