If you like fiction (and Stephen King for that matter), you should read 11 22 63. Main character goes back in time to change past events and things… sort of work out. It has a cool take on time travel and course of events in general, I was a big fan of reading it.
There is also a mediocre tv adaption of it as well if you’re not into fiction, but I didn’t finish it.
How is it good? I, personally, want a human to narrate a story to me. At the very least I would know somebody got paid to do this job.
