Sir Gawain is the thin line incarnate between devout Christian and chaotic bisexual. And unfortunately this long distance relationship with the Green Knight won't work out for him.

That's it. That's the review.

I remembered the essentials of this from high school English, but rereading it, I was struck by the beauty of the language and the structure of the poem - the longer lines accentuated by the “bob and wheel” as my edition calls the short lines and the end - it works so well. Example:

Lines 107-124 talk about the feast of King Arthur and his Round Table knights.

...
With a flaring crack of trumpets the feast
Began, trumpets all hung with bright banners,
And drums beat, and glorious bagpipes
Rumbled and shrilled their quick-step tunes,
And hearts beat quick with the music. At the signal
Rare and delicate dishes were served,
And venison in great slabs, and so many platters
That there was almost no place to set them in front of
The guests, broths and stews in overflowing
Abundance.
All ate as they pleased
And as much as they wanted,
A dozen dishes apiece,
And beer and wine flowed free.

I’m not so concerned with any allegorical meaning; I just enjoy the poem for the language and the setting and the story - and a cracking good story it is, too!
