Nowadays we all know the disadvantage of "love across the internet" ... it doesn't often work out.
However You've Got Mail .... which is a re-make of Shop Around The Corner and was filmed in a time when e-mails, and chat rooms were fairly new. Both films have 2 people who "hate" each other in real life, writing to each other ... and falling in love.
Both films show that sometimes we let our appearances hide our true feelings. I love both films ... as I think most of us (or is it just me) would love to have someone that you can connect with truly, whatever else is going on in the world.
