If you watch "x" backwards, it's about...

If you watch Stuart Little backwards, it's about how a mouse causes so much trouble, his family decides to disown him and put him up for adoption.

 

If you play KH:Re:CoM backards, it's about a guy who abandons the blonde girl and makes new memories, and leaves the castle more confused than when he started.

 

If you watch the first season of Sengoku BASARA backwards, Oda Nobunaga is the protagonist.

 

If you watch Persona 4 backwards it is about a group of friends who saved their town but then start going their separate ways and forgetting about their powers and each other.​

 

If you watch Godzilla backwards, it's about a big lizard monster coming out of the ocean, destroying a bunch of stuff, and then going back into the ocean.... wait.... isn't that how it is forwards?

 

I think what you meant was:

If you watch Godzilla backwards, its' about a giant lizard that fixes buildings with his tail and claws, then goes into the ocean and becomes a normal lizard.

 

It depends on which Godzilla you watch.... there are a million of them.

 

Same basic concept though.

 

If you play Kingdom Hearts 2 Backwards...
It's about a brunette haired boy who helps this organization achieve Kingdom Hearts, while summoning heartless and nobodies with his magical, but evil keyblade. He goes around all these worlds, destroying them with the heartless and nobodies before finally going back to sleep in this pod in a place called Twilight Town. But then the boy wakes up in a bed, with blonde hair instead and he realizes it was all just a dream and that it never really happened.
