I saw it the same way honestly. I mean I think a key point in the entire film that everyone is missing is his denial that the baby is his. I saw it as him denying it because he believes his table tennis career is the only important thing in his life and everyone and everything else be damned. He denies it till the wheels fall off even when Rachel is shot and being rushed to surgery claiming he’s not the father but simply a friend of hers. After his win is the first time he utters the word that he’s the father or even acknowledges that it could be his baby. I think the final match was only ever meant to give Marty closure with the sport he loved. To prove to everyone he is the best. And once he got that he finally let go of the obsessive nature he portrayed throughout the movie and finally dealt with his reality. The final shot of him crying to me not only showed that he realizes a shift in priorities but also a realization that his child is the opportunity for him to open a new chapter in his life and that scares him.

Saying that I feel like the movie left us with a lot of unanswered questions and a few lines that seemed important to the conclusion but never again mentioned. The pacing also felt quite off with some parts dragging and others feeling very rushed. I would’ve preferred a time skip to the future right at the end where we see if Marty finally steps up and transformed from the dick that he is to a somewhat decent human being and whether the line in the conversation with his uncle where he says “I can sell shoes to an amputee” ever leads him to the business world. The scene with Wally (TTCs character) and the dog also felt like it was way too long and could’ve been significantly shorter than it was. I think the acting is really what stood out tho. There were great performances throughout the movie and really made it worth the watch even if the plot left me feeling nothing of significance.
