Is There a Time Travel in the Movie?

Time travel was unnecessary. The entire rest of the movie would have worked. I will say that i can understand where they were coming from with this twist. A having looki think they should have done it. It was dumb. But i understand where they come from, because a having a antagonist with a, you know, a connection to the protagonist makes things stronger. In this one, he's not his father, but he's like an old version of himself,. which is cond ik a aer sort of reference, anta ret con. To me, yes.
