\"Time loop\". How is that?

White Wine Taster
uh ... because the movie has huge problems with logic? Purely logically, if young Joe decided not to kill the boy and change his future, then everything would have to end there, old Joe would have to disappear, etc. If this did not happen, then, therefore, the future in which Bruce Willis was formed is invariable and all his attempts to change something in the past are meaningless. Just as it would be impossible to kill old Joe by killing young Joe for that. But that's exactly what happens at the end.

And this is not the only inconsistency. Well, they send bodies to the past to hide. Already in itself delirium. Anyway. I don't remember exactly, but why the heck send them there alive? With corpses no less fuss? And why the hell, then, did they not hesitate to kill Willis' wife if there were so many problems with future murder?

In general, looking for logic in this film is a thankless and senseless task)

And yes, Sid is not Joe
