A miner investigating a vein of gold must bring his team of five back to safety when a string of seemingly paranormal occurrences drives the men to insanity.

Absolutely intrigued!

The mystery for me is the dog that isn't barking. To wit, how come the protagonist is the only one not driven to insanity?

Your logline suggests the inciting incident is a string of paranormal occurrences that sends his team insane ... so if they're insane, what does "bringing them back to safety" look like? And if the "safety" is just escaping the ghosts (or whatever they're encountering) ... why don't they just leave the mine? What is making that difficult?

There's no clear antagonist, beside a vague force, but I guess with ghost movies that's not so crucial? I'm not certain on that one ...

What else do you know about the miner? Is there some way to make him the ironic protagonist, or else give us a little more indication of the internal journey he's likely to experience?

"When a string of paranormal occurrences haunts a pragmatic miner and his team, He must lead his crew to safety even as his workers delve deeper into madness."

I would shorten it further & dump the 'seemingly paranormal' and replace it with 'freakish' or 'strange'. I think the first option is scarier. Your logline suggests a horror-thriller genre [correct me if I am wrong], so tight and scary is best.

Nice work. The criticism is "the stakes". What if the protagonist fails.
Why must they achieve what they have set out to achieve?
And why must they achieve it *now*.
What genre is this? Is this a dark genre? Or an animated feature for kids? This doesn't come across in the logline.
Also, "Team of five", plus the protagonist, plus (one or more) antagonists, it's an ensemble, or else there could be some non-essential characters here. Suggest no more than 5 (total) in the team, and don't specify the number "five" in the logline.
Other than that, "Great job! Attaboy! You can do it!"
Or a personal one from me.
"Don't take it too personally. It's not YOU that suck. It's not your VISION that sucks, it's just that your logline needs a little work. There's hope for you. Suggest that you subscribe to Karel Seger's Blog, The Story Department". I haven't seen you post before. Are you new here?

Hi Karel... Big fan of this site -- insightful, helpful, addictive, great contributions from some obviously talented and intelligent folk. Huge thanks.

Now to the logline (I kinda feel like a haughty customer trying to tell a barman how to pour a beer...;) )...i

I see the potential, it has the markings of a very tense and claustrophobic ride -- but I think I'd be more intrigued if I knew what the paranormal activities (well, seemingly paranormal...) actually were, also, if the team's 'insanity' was more clearly defined...

How does their insanity prevent him from getting them back to the surface? Is his main action counseling them? Is he trying to round them up because they've gotten lost? Are they blubbering messes in the corner? Do they think they're farm animals, or are they trying to kill each other (and him)?

And once the team have become insane, how is the paranormal activity a threat to him? As in, why isn't he insane? ...what's the bigger threat, the paranormal activity (and what's causing it) or the team?

Anyway, thanks again for an awesome site, and best of luck with it.

Simply introducing your hero as "a miner" doesn't give me any characteristic or character flaw that make me root for him. Other than that, great clear logline.

This almost precisely describes the plot of "Armageddon".

Think about it.
