Here is a list of things that you will often find in romantic movies. If you like you can use it as a "spot the typical"-game. One point for each thing. If you play against each others you can see who found the most items. Or if you prefer you can calculate a score on how typical the film you just saw was.
WARNING! This should not be treated as a drinking game where you take a drink every time you spot a thing from the list! If you do would probably end up in a hospital or worse, even dead. I do not take any responsibility if you do and DON'T TAKE THIS AS A CHALLENGE. SERIOUSLY!
