After critiquing a bunch of other people's loglines, an optimistic screenwriter must improve his own poorly written ideas or wallow in unemployment forever. But what seems like a simple task soon reveals itself to be much harder than first anticipated …

Giggles.

Have you been researching my life for this logline?

It needs shortening. I suggest:

In a "Groundhog Day" meets 'Jaws' scenario a formerly optimistic screenwriter is doomed.

New title: Chewed It Up and Spitted It Out, Again... and Again... and Again...

That would be CUSOAaAaA!

I suggest you seek Geno, the Shark-Eating Man guy. If nothing else his fingernails on the chalkboard routine will snap you out of your stupor.
