-A group of international tourists are taken off the beaten path to an isolated village deep in the Vietnamese countryside where they experience a Viet Cong tunnel crawl that makes the famous Cu Chi tunnels seem like a playground… tighter, more claustrophobic, scarier. They get their money’s worth and then some!

Unfortunately this doesn't sound like a logline for a feature film. There is no hero, antagonist, struggle, goal, etc. It sounds like the description of an event on someone's holiday. At best it could be the lead-in to a segment on a travel documentary but even then it lacks a purpose. It is really just the 'place' element of a logline. It needs all the other ingredients. It could be a horror film set in the tunnels when the young couple on their holiday discover a secret passage that leads to a.... you get the idea.

The first sentence sounded promising for a moment but sadly the logline goes downhill from there... to reach the absolute lowest point with ... the exclamation mark.

Please. Don't. Ever.
