I watched the 2017 version of Shakespeare's play, which is set in a boarding school in a conservative Christian community. It made me laugh right away with the Bad Girls Get Diseases/Good Girls Don't poster. In fact, there are several scenes that match Monty-Python sex-ed-talk levels.
There are naturally four male students and four female students who flirt and court. In truth, the relationships are rather touching, in part because they are so young. The same behavior in older characters would be kind of wearing and tacky and exasperating, which may explain why Branagh's version of this play was not successful (but his Much Ado, which is more witty and challenging, was).
It is rather sweet to watch bumbling and gawky and frankly horny teenage boys gain a measure of maturity--to watch them grow from wanting to date any girl to being enamored of a single young woman with whom they want to spend time.
So one lady can encourage Berowne to stop making snide remarks about people and use his wit to help them instead; the final scene of the movie shows him visiting cancer kids and using his clever (self) mockery to cheer them up. Likewise, after the princess's father dies, her beau attends the funeral to give her comfort. Everybody grows up a little.
It is less sweet to watch older folks going through the same ups and downs--which is why Midsummer Night's Dream is funny but has a seriously dark side.
