Word/slang for person who cries easily watching movies

I'd like to know from native speakers what would they call or what slang would they use for a person who cries easily watching even the silliest of movies (meaning very little drama). For example, watching Home Alone when Kevin meets his family again.

Solution 1:

I'd normally call them a sap. Meaning someone who is overly emotional and cries at the slightest sad thing. However I can't find that definition in the dictionaries I looked at. I will also note that a "sappy" movie is one that plays to one's emotions in an effort to elicit a response- like crying:

For example here's sappy used "in the wild" (thanks @Conrado):

Everyone needs a good cry every now and then. Especially since it’s summer and we have plenty of time on our hands to watch sappy movies, eat chocolates and bury our sorrows.

Solution 2:

an emotional person is prone to emotions.

emotional - (adjective) "readily affected with or stirred by emotion: an emotional person who often weeps."
