"An 86 year old man relives his past lives through hypnotic regression, but in one fateful session, a blurry vision shows him his possible next life and that his current one is about to end soon and the strange man from an unknown agency has to make the toughest moral decision."

I think it’s very clear who’s who in this. Just because someone has to make a decision doesn’t mean they’re the protagonist. We’re trying to peak the interest aren’t we? I put it into the readers mind that a decision has to be made from the questions at the beginning and then reminded them again at the end. Just because one character has to make the decision, the other one could have the conflict about it, right?
This may be better for the back cover of the book is what I’m gathering.
Also, in all of these comments you’re assuming the plot… and by that notion I guess I actually did my job because it means you’re wondering about it.

Let’s talk about the ideas also and not just the mechanics of writing them. The mechanics or writing these lines is OK, but putting it into rigid rules, especially something only a few lines long is kind of weird. If I look at the reasons to do these lines, is that it is to quickly pitch an idea to someone interested in further helping you develop your work. Now, what you’re expecting here is a plot synopsis.. I’m guessing? You’re talking about multiple acts in a movie in only a short paragraph.

Many of the loglines here are not engaging and interest me to know more and frankly, give me less information than I have just given you. And the lot of them are 30 words or less.
