What's the word to describe when movies try hard to evoke emotion?

I like the word mawkish

sentimental in an exaggerated or false way.

An Example Usage

The Best Of Me, film review: Terminally mawkish tearjerker is hard to stomach

Much of the dialogue for this terminally mawkish tearjerker sounds as if it has been taken directly from a Dolly Parton or Whitney Houston song ...

The etymology of this word is

mawkish (adj.) 1660s, "sickly, nauseated," from Middle English mawke "maggot". Sense of "sickly sentimental" is first recorded 1702.

'Melodramatic' - most commonly used for movies where emotions interspersed with exaggerated characters, cheesy lines, catchy music and background scores are used to create sensations.

"It makes me sick when movies with unrealistic and melodramatic endings become huge hits."

Others words can be - saccharine, sugary, maudlin, sloshy, sloppy, rabble-rousing

Schmaltz was mentioned earlier.

I submit sappy:
